b) 15/16
c) 31/32
d) 11/16​
give the answer with an explanation plz!​

Answer 1

Answer:

Option(C)

Step-by-step explanation:

When 5 coins are tossed, the sample space is given by

n(S) = 2⁵ = 32

Getting at least one tail:

Probability of getting all heads = HHHHH = 1

Required probability = (1/32)

Now,

Probability of getting at least one tail :

= 1 - P(all heads)

= 1 - 1/32

= 31/32

Therefore, required probability = 31/32

Hope it helps!
