If a fair coin is tossed 10 times, find the probability of(i)         exactly six heads        (ii)        at least six heads(iii)       at most six heads

Text Solution

Verified by Experts

p = Probability of getting head = `1/2`
q = Probability of getting toss = `1/2`
Total number of tosses n = 10
(i) Probability of exactly six heads = `^n C_6 p^6 q^4` = `^10 C_6 (1/2)^6 (1/2)^4` ...
