Answer:
P=number of favorable outcomes/number of possible outcomes
P1.
a. P(blue)=6/18 divided by 6= 1/3 or 33.33%
Therefore, the probability of picking a blue ball is 33.33%, less likely to happen.
b. P(notred)=10/18 divided by 2= 5/9 or 56%
Therefore, the probability of picking a ball that is not red is 56%, equally likely to happen.
P2.
P(even)=10/20 divided by 10= 1/2 or 50%
Therefore, the probability of picking an even number is 50%, equally likely to happen.
P(odd)= 10/20 divided by 10= 1/2 or 50%
Therefore, the probability of picking an odd number is 50%, equally likely to happen.
