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
I think its not sure: 42.437m
p% × 60 = 15
p/100 × 60 = 15
6p = 150
p = 25
therefore value of p is 25
