Answer 1

Step-by-step explanation:

HERE

Total outcomes = 14

ANSWER (a)

Probability of drown white marble= 5/14

ANSWER (b)

Probability of drown either red or Blue = 7/14

ANSWER (c)

Probability of drown green marbles = 2/14

Answer 2

Answer:

We know that, P(E)=No. of the required outcomes/No. of all possible outcomes

So, a. No. of white balls=5

Total no. of balls in the jar=3+4+5+2=14

◆P(ball drown from the jar is white)

= No. of white balls/Total no. of balls in the jar

=5/14

b. No. of Red and Blue balls=7

Total no. of balls in the jar=14

◆P(balls drown from the jar is either red or blue

=No. of Red and Blue balls/Total no. of balls in the jar

=7/14 =1/2

c. No. of green balls=2

Total no. of balls in the jar=14

◆P(ball drown from the jar is green)

=No. of green balls/Total no. of balls in the jar

=2/14 =1/7
