Question

A bag contains 19 red balls, 37 blue balls and 27 green balls. If a ball is picked up from this bag at random, what is the probability of picking a blue ball?
(1) 36/87 (2) 37/83
(3) 38/83 (4) None of these

Answer 1

Answer:

37/83

Step-by-step explanation:Total cases: 27+37+19=83.

Possible cases: 37.

Probability= possible cases/ total cases.

Probability=37/83.

Answer 2

2) 37/83
explanation :-
Total balls in a bag = 83 balls
there are 37 balls in a bag
hence, n(S)=83
n(A)=37
p(A)=n(A)/n(S)

=37/83
