p(e)=possible required events/total events. Getting at most Two heads means 0 to 2 but not more than 2. 7/8? P(E)= N(E) /N(S) = 7/8 Ans….

When three unbiased coins are tossed the probability of receiving exactly one tail is?

There are 8 total possible outcomes for flipping three coins, and 3 of the 8 scenarios have one tail in them (THH, HTH, HHT). The answer is 3/8.

What is the probability that two heads occurs when two unbiased coins are tossed?

0.5 x 0.5
The probability of getting two heads on two coin tosses is 0.5 x 0.5 or 0.25.

When three unbiased coins are thrown find the probability of getting at least two tails?

Originally Answered: Three unbiased coins are tossed once. What is the probably of getting at most two tails or at least two heads? Possible outcomes for getting at most 2 tails are (HHT),(HTH),(HTT),(THH),(THT) &(TTH) and the required probability is 6/8.

When 3 unbiased coins are tossed together once?

When we toss three coins simultaneously then the possible of outcomes are: (HHH) or (HHT) or (HTH) or (THH) or (HTT) or (THT) or (TTH) or (TTT) respectively; where H is denoted for head and T is denoted for tail.

When 3 coins are tossed possible outcomes is?

The number of different outcomes when three coins are tossed is 2 × 2 × 2 = 8. All eight possible outcome are HHH, HHT, HTH, HTT, THH, THT, TTH, and TTT.
