Answer:
here's the answer
Step-by-step explanation:
total outcomes = 1,2,3,4,5,6,7,8,9and 10
favourable outcomes = 2,3,5 and 7 ( prime no. s from 1 to 10 )
probability of getting a prime number marbles
= no. of favourable outcomes
-----------------------------------------------
no. of total outcomes
= 4/10 = 2/5
