katex is not defined black ball drawn at random the probability =katex is not defined
katex is not definedblack ball drawn at random the probability =katex is not defined
katex is not defined black ball drawn at random the probability = katex is not defined
katex is not defined
Ans. (c)
Explanation:
A = {2, 4, 6, 8}
B = {8}
katex is not defined
Explanation:
Let A and B be two independent events. Then,
P(A ∩ B) = P(A) × P(B) = katex is not defined
Explanation:
Here, katex is not defined
and P(A ∪ B) = P(A) + P(B) – P(A ∩ B)
⇒ katex is not defined
Explanation:
Let A, B, C be the respective events of solving the problem.
Then, katex is not defined Here, A, B, C are independent events.
Problem is solved if at least one of them solves the problem.
Required probability = P(A∪B∪C)
= 1 - P(A’) P(B’) P(C’)
katex is not defined
