There are 75 marbles in a bag.
15 are blue, 30 are red, 20 are orange and 5 are yellow.
What is the probability you would pick a yellow or a blue marble, in simplest form?
4/15
400
I flipped a coin 75 times. I got heads 40 times and tails 35 times.
Compare the experimental probability of landing on heads to the theoretical probability of landing on heads.
Experimental: 40/75=8/15=0.53=53%
Theoretical: 1/2=0.5=50%
The experimental probability is greater than the theoretical probability
