26. India plays two matches each with West Indies & Australia . In any match the probabilities of India getting point 0, 1 & 2 are 0.45, 0.05 & 0.50 respectively. Assuming that the outcomes are independents, the probability of India getting atleast 7 points is :
(a) 0.8750 (b) 0.0875 (c) 0.0625 (d) 0.0250
Answer
Answer : (b)

Explanation : No answer description available for this question. Let us discuss.
Probability » Exercise - 113. If A & B are any two events, then the probability that exactly one of them occur is : (a) P (A) + P (B) - P (A ∩B) (b) P (A) + P (B) - 2 P (A ∩B) (c) P (A) + P (B) - P (A ∪B) (d) P (A) + P (B) - 2 P (A ∪B)
Probability » Exercise - 111. If A & B are any two events, then the true relation is : (a) P (A ∩B) > P (A) + P (B) - 1 (b) P (A ∩B) < P (A) + P (B) (c) P (A ∩ B) = P (A) + P (B) − P (A ∪ B) (d) none of these
Probability » Exercise - 15. 6 coins are tossed simultaneously . The probability of getting atleast 6 heads is : (a) 57/64 (b) 229/256 (c) 7/64 (d) 37/256
Probability » Exercise - 115. The probability of happening atleast one of the events A & B is 0.6. If the events A & B happens simultaneously with the probability 0.2, then (a) 0.4 (b) 0.8 (c) 1.2 (d) none of these
Probability » Exercise - 19. If P (A) = 0.4, P (B) = x, P (A ∪ B) = 0.7 and the events A & B are independent, then x = (a) 1/3 (b) 1/2 (c) 2/3 (d) none of these
Probability » Exercise - 113. If A & B are any two events, then the probability that exactly one of them occur is : (a) P (A) + P (B) - P (A ∩B) (b) P (A) + P (B) - 2 P (A ∩B) (c) P (A) + P (B) - P (A ∪B) (d) P (A) + P (B) - 2 P (A ∪B)
