Q80.An ordinary dice is rolled for a certain number of times. If the probability of getting an odd number 2 times is equal to the probability of getting an even number 3 times, then the probability of getting an odd number for odd number of times is: (1) 1 (2) 5 32 16 3 1 (3) (4) 16 2
What This Question Tests
This question involves applying the binomial probability distribution to find the number of trials and then calculating the probability of getting an odd number an odd number of times.
Concepts Tested
Formulas Used
P(X=k) = nCk * p^k * (1-p)^(n-k)
