Two six-sided dice are rolled. Find the probability the first die came up a 2 and the second die came up a 5
1/9
1/18
1/36
1/12
- 1/36.
There are 6 possibilities for the first die and 6 possibilities for the second die. Hence there are 6 * 6 = 36 possible dice rolls. There is only one of them: (2,5) which has 2 on the first die and 5 on the second die. Thus the probability is 1/36.

How likely it is that a certain event will occur.
A branch of mathematics concerned with numerical data.
A branch of mathematics concerned with data.
How likely it is that a certain number will be chosen at random.
How likely it is that a certain event will occur.
- , probability is defined as 'The quality or condition of being probable; likelihood.'. 'Statistics' refers to a branch of mathematics concerned with data, but not necessarily numerical data.

what is the probability of a meteor hitting earth
1. 1 in 200,000
2.3 in 400,000,000
3.1 in 300,000
4. 1 in 102,430,800,2170.5
Therefore, the chance that such an object will hit us in any given year is roughly 1 in 300,000

Two six-sided dice are rolled. Find the probability that one die came up a 2 and the other came up a 6.Hint
1/36
1/9
1/12
1/18
- 1/18.
This event consists of the outcomes (2,6), (6,2). Hence it has probability 2/36 = 1/18

You toss a coin four times. The first, second and third toss are heads. What's the probability of the fourth toss also being heads?
- 1/2.
The result of the first three tosses doesn't influence the fourth. The odds between heads and tails are always even.

what is the probability of another earth like planet?
1. 1 in 100 billion
2. 1 in 100 billion
3. 1 in 600 billion
4. 1 in 60 billion
4. 1 in 60 billion
Similarly, for Earth to have been the only case of hosting a technological species over the history of our Galaxy, the odds of a habitable zone planet ever hosting a technological species must be less than 1.7×10−11

Two six-sided dice are rolled. Find the probability that at least one die is a 3.Hint
1/3
1/2
11/36
1/6
- 11/36.
The probability that the first die is 3 is 1/6, the probability that the second die is 3 is 1/6, and the probability that both dice are 3 is 1/36. By the principle of inclusion/exclusion, the probability that the first die or the second die is 3 is just 1/6 + 1/6 - 1/36 = 11/36. This probability is useful in backgammon - this is the probability of entering off the bar when there is only one open point in the opponent's table.

5/18
- 5/36.
The outcomes in the event "the sum is 8" are: (2,6), (3,5), (4,4), (5,3), and (6,2). Since there are 5 ways the sum can be 8, the probability is 5/36.

Two six-sided dice are rolled. Find the probability that their sum is not 7.Hint
5/6
2/3

23/36
- 5/6.
The ways in which a 7 can be rolled are: (1,6), (2,5), (3,4), (4,3), (5,2), and (6,1). There are 6 ways a sum of 7 can be rolled. There are 36 total dice rolls, thus there are 30 ways a sum of 7 cannot be rolled. Hence the probability is 30/36 = 5/6.

The time is 8pm. I am reading a book which was published in 1976. In a minute I will watch a programme on Channel 4. What is the median of all those digits (8, 1, 9, 7, 6 and 4)?Hint
6.5
7
6
6 and 7
- 6.5
To find out the median of a set of numbers, put the numbers in order, starting with the smallest. 1, 4, 6, 7, 8, 9 is the correct order. You then find the middle number. There are 6 numbers, so the middle is halfway between the third and the fourth numbers. Halfway between 6 and 7 is 6.5, so 6.5 is the median.
