what is the probability of raining today?
3/5
Given a 4 color spinner with equal parts. One part is coloured green. So what is the probability of not spinning the green part?
3/4
Probability of drawing a card with a 2,3 or 4 on it?
12/52 = 3/13

3/6 = 1/2
What is the word meaning having a set of outcomes in a chance experiment?
An Event
For a bag filled with jelly-beans.
The probability of picking a pink jelly bean is 4/57
What is the probability of not picking a pink jelly bean? SHOW YOUR WORKING OUT
P(not pink) = 1 - 4/57
P(not pink) = 53/57
You have a bag of marbles, there are 17 marbles and 4 of them is green. What is the probability of not picking a green marble?
13/17
Probability (not an ace)= ?
48/52 = 12/13
P(not a factor of 6)= ?
2/6 or 1/3
4 and 5 are not factors of 6, therefore it is 2/6
Outcomes of a chance experiment that do not have equal chance of happening.
What is the question for this statement?
What are non-equally likely outcomes?
If the probability of picking a 6 is call P(6)
what is the expression for the probability of not picking a 6?
1 - P(6)
You have a bag of 55 marbles and 5 of them are red. If the rest of the marbles are divided in 5 equal parts (blue, green, yellow, white and black). What is the probability of randomly picking a yellow marble?
10/55 = 2/11
