Probability=number of specific outcomes/total possible outcomes
And the probability of two events happening at the same time is P(1)*P(2), or the product of the probabilities of each event...
In this case:
P(primary color)=3/6=1/2
P(head)=1/2
P(primary and head)=(1/2)(1/2)=1/4
Answer:
Answers below

<span>To solve this problem you must apply the proccedure shown below:
1. You have the following information given in the problem above:
- There are 75 classmates.
- 56% of his 75 classmates like salsa music and 80% of his 60 relatives like salsa music.
