Assuming this is a 6-sided die:

(a) 1/6 = 0.167 or 16.7 %
(b) zero (numbers on the die are 1-6)
(c) 3/6 = 50% (can be 2, 4, or 6)
(d) 3/6 = 50% (of the numbers you could roll, 2, 3, and 5 are prime)

liq [111]

The probability of getting exactly zero tails is 1/8.

Step-by-step explanation:

When a fair coin is tossed three time, the set of equally likely outcomes is:

S= {HHH,HHT, HTH, THH, HTT, THT, TTH, TTT}

n(S)=8

Let A be the event that there are exactly zero tails which means there are all heads

Then

A= {HHH}

n(A)=1

P(A)=\frac{n(A)}{n(S)}\\=\frac{1}{8}

The probability of getting exactly zero tails is 1/8.
