3 coins can land in 8 different ways. Only one of these ways is all tails.

So the probability of rolling at least one heads is 7/8 = 87.5% .

Probability of getting 1 head tossing two coins?

By tossing two coins the possible outcomes are:H & HH & TT & HT & TThus the probability of getting exactly 1 head is 2 out 4 or 50%. If the question was what is the probability of getting at least 1 head then the probability is 3 out of 4 or 75%


When tossing 5 coins simultaneously what is the probability that at least 1 head is showing?

Probability of no heads = (0.5)^5 = 0.03125Probability of at least one head = 1 - probability of no heads = 1 - 0.03125 = 0.96875

When tossing 5 coins simultaneously can you find the probability that at least 1 head is showing?

Probability not at least 1 head showing is when all 5 coins are tails: (1/2)5=1/32 Therefore probability at least 1 head is showing is 1-1/32=31/32

When tossing 3 coins simultaneously find the probability that at least 1 head is showing?

No matter how many coins are thrown, the possibility of having AT LEAST ONE 'head' is 50%. This changes if you specify the number of 'heads' that must be shown.

When tossing 5 coins simultaneously find the probability that at least 1 head is showing.?

This is easiest to solve by working out the probability that no heads show and subtracting this from 1 to give the probability that at least one head shows: Assuming unbiased coins which won't land and stay on their edge, the probability of head = probability of tail = ½ → probability no heads = probability 5 tails = ½^5 = 1/32 → probability of at least one head = 1 - 1/32 = 31/32 = 0.96875 = 96.875 % = 96 7/8 %


What is the probability that you toss a head or a tail?

Two coins are tossed. What is the probability of tossing at least one head?

There are 2 coins, 1 and 2. Each has two possibilities, H or T. The possibilities are: 1H, 2H 1H, 2T 1T, 2H 1T, 2T Each possibility has an equal chance of happening. The chance of tossing at least one head is 3/4.
