1.	Two coins are tossed simultaneously. Find the probability of getting(i) exactly 1 head(ii) at most 1 head(iii) at least 1 head
Answer» Two coins are tossed: Sample space = {HH, HT, TH, TT} Total number of outcomes = 4 P(getting a tail) = 1/2. Now, (i) P(exactly 1 head) = 2/4 = 1/2 (ii) P(at most 1 head) = 3/4 (iii) P(at least 1 head) = 3/4

Two coins are tossed simultaneously. Find the probability of getting(i) exactly 1 head(ii) at most 1 head(iii) at least 1 head

Answer»

Two coins are tossed:

Sample space = {HH, HT, TH, TT}

Total number of outcomes = 4

P(getting a tail) = 1/2.

Now,

(i) P(exactly 1 head) = 2/4 = 1/2

(ii) P(at most 1 head) = 3/4

(iii) P(at least 1 head) = 3/4
