Answer 2

Answer:

3/4

Step-by-step explanation:

To Find: In a simultaneous throw of two coins the probability of getting at least one head

Solution:

Total outcomes={HH,HT,TH,TT}=4

Favorable outcomes(atleast one head)={HT,TH,HH}=3

Probability of getting atleast one head = favorable outcomes/total outcomes

                                                              =3/4

Hence Probability of getting atleast one head is 3/4
