Accepted Answer

Correct answer: D. (d) JEE Main 2019 P (at least one hit the target) =1-P (none of them hit the target) =1-(1- 12)(1- 13)(1- 14)(1- 18) =1- 12 23 34 78=1- 732= 2532

$Four persons can hit a target correctly with probabilities \frac{1}{2}, \frac{1}{3}, \frac{1}{4} and \frac{1}{8} respectively. If all hit at the targetindependently, then the probability that the target would be hit, is:$
