Question

(Please answer ASAP) A bag contains three red marbles, five green marbles, and two blue marbles.

a. What is the probability of getting a red marble?

b. What is the probability of NOT getting a red marble?

Answer 1

a. 3/10

b. 7/10

Explanation:

a. Total number of marbles = 10

Number of red marbles = 3

Probability = Number of outcomes/ Total number of outcomes

= 3/10

b. Total number of marbles = 10

Number of red marbles = 3

Number of marbles excluding the red marbles

= 10 - 3 = 7

Probability = Number of outcomes/ Total number of outcomes

= 7/10
