a Two coins tossed Probability of obtaining one tail b Two c

a) Two coins tossed. Probability of obtaining one tail?

b) Two coins tossed. Probability of obtaining at least one tail?

c) Two coins tossed. Probability of obtaining at most one tail?

d) Two dice rolled. Probability of obtaining a double?

I awarded extra points for the four questions. If you could explain, I\'d appreciate it

Possible outcomes: (HH) (HT) (TH) (TT)

1. 1 tail means either (HT) or (TH)

So, P=1/2

2.atleast 1 tail means either (HT) or (TH) or (TT)

So, P= 3/4

3.atmost 1 tail means either (HT) or (TH) or (HH)

So, P= 3/4

4. Total outcomes = 36

Doublet outcomes= 6

So, P= 1/6
