Q80.Each of the persons A and B independently tosses three fair coins. The probability that both of them get the same number of heads is: (1) 5 (2) 1 8 8 (3) 5 (4) 1 16
What This Question Tests
This question requires calculating the probability of getting a certain number of heads in three coin tosses and then finding the probability that two independent individuals get the same number of heads.
Concepts Tested
Formulas Used
P(X=k) = C(n, k) p^k (1-p)^(n-k)
P(A and B) = P(A) * P(B) for independent events
