Step-by-step explanation:

ANSWER ::

Total number of marbles = 10

So the total number of possible outcomes = 10

Let A be the event that the marble is blue

Then the possible outcomes for A is = 3

So the required probability is = 3/10

Answer 2

Answer

Total number of outcomes = 5+2+3 = 10

If a marble is selected randomly,

Favourable number of outcomes = 3

probability of blue marble = favorable outcomes/total number of outcomes

= 3/10
