Question

two different coins are tossed together find probability of getting 1)both tails 2)one head 3)
at least one head
​

Answer 1

2. the probability of getting exactly one head is 21.

1.. Probability of getting two heads or two tails = 2/4 = 1/2

3.

If you want to know what the probability is to get at least one Heads, then that is the same as the probability of all the events (100%, or 1) minus the probability of getting all Tails.

Answer 2

The probability of both tails ,one head, and at least one head is -- n(A) =1, n(B) =2, n(C) =3.

Step-by-step explanation:

S={HH, TT, HT, TH}

A={TT} n(A) =1

B={HT, TH} n(B) =2

C={HH, HT, TH} n(C) =3
