QUESTION-3

1. QUESTION

A player can take a maximum of 4 chances to hit a bottle with a flying disc. The probability of hitting the bottle at the first, second, third and fourth shots are 0.1, 0.2, 0.35 and 0.45 respectively. What is the probability that the player hits the bottle with the flying disc?

A)0.6573
B)0.2574
C)0.7426
D)0.3427

Explanation

(C)

= According to the question

Probability of missing the target in the second shot = 10.2 = 0.8

Probability of missing the target in the third shot = 1-0.35 = 0.65

Probability of missing the target in the fourth shot = 10.45 = 0.55

Probability of hitting the target = 1- (Probability of missing the target)

1-(    ? x 0.8 x 0.65 x 0.55)

= 1-0.2574

0.7426

Thus, 0.7426 is the correct answer. Hence, this option is the correct answer.
