Question

There are 15 marbles in a box with numbered from 1 to 15 marked on each of them.
(a) What is the probability of drawing a marble with an even number on it?
(b) What is the probability of drawing a marble with a prime number on it?

Answer 1

A)NUMBER OF EVEN FROM 1 TO 15=2,4,6,8,10,12,14

SO PROBABILITY OF EVEN IS 7/15

B)PRIME NUMBERS TILL 1 TO 15=2, 3, 5, 7, 11, 13.

SO PROBABILITY IS 6/15

Answer 2

Step-by-step explanation:

Number of marbles =15

Number of even numbers = 2,4,6,8,10,12,14

So probability of getting an even number is 7/15

Number of marbles = 15

Number of prime numbers =2,3,5,7,11,13

So probability of getting prime number = 6/15

Note - 1 is not a prime number nor an even number
