If the same pair of coins is tossed again at random, find the probability of getting :
i) two heads
(ii) exactly one head
(iii) no head.​

Answer 1

Answer:

1) 21 /100

2)55/100= 11/20

3)24/100=6/25

Step-by-step explanation:

probabilityprobability of getting 2 heads = number of favourable outcome over total number of outcome

21/100

probability of getting exactly one head = number of favourable outcome over total number of outcome

55/100=11/20

probability of getting no head = number of favourable outcome over total number of outcome

=24/100=6/25
