Ex 16.3, 8 Three coins are tossed once. Find the probability of getting 3 heads If 3 coins are tossed various combination possible are S = {HHH, HHT, HTH, THH, HTT, THT, TTH, TTT} n(S) = 23= 8 Let A be the event of getting 3 head A = {HHH} ∴ n(A) = 1 Probability of 3 heads = P(A)

6.7 powerstroke cp4 bypass installThe probability of getting exactly two heads when three fair coins are thrown simultaneously is $3/8$. Each coin has a probability of $1/2$ for being a head, or for being a tail, and there are three coins that could be the head. An observer not being able to identify the coins does not change that.

\probability" is intended to be the probability that the corresponding outcome occurs (see Section 4.4.4). In sport, coins are tossed to decide which end of the ground a team is to defend, or who is going to go into bat ﬂrst. It is quite common to call the outcome after the coin has been tossed, but before it has fallen. Even with a
