Question

You have 15 pennies in your pocket. Of those pennies, 3 are Canadian. Suppose you pick a penny out of your pocket at random. Find P(not Canadian)

Answer 1

this your answer hun

P ( canadian)= 3/15 = 1/5
-> P(not canadian) = 1 - 1/5 = 4/5

Answer 2

P(Not Canadian) = 0.8

Explanation:

Be the events

C = the penny is Canadian

NC = the penny is NOT Canadian

The probability of an event is equal to the successful events among the total events.

`P(C)=(3 (Canadian Cents))/(15(Cents in total))=(3)/(15)=0.2`

The sum of the total probability is 1. Then,

P (NC) = 1 - PC = 1 - 0.2 = 0.8

The probability that a random penny is non-Canadian is 0.8

Hope this helps!
