Pr(At least one head in 3 tosses) = 1 - Pr(No heads in 3 tosses)
= 1 - Pr(3 tails in three tosses) = 1 - [Pr(T)*Pr(T)*Pr(T)] since the three tosses are independent.
= 1 - 1/2 * 1/2 *1/2 = 1 - 1/8 = 7/8

What is the probability of getting no heads when you toss a coin 4 times?
1 out of 16
Tossing a coin 9 times and getting tails what is the probability of getting tails on the next toss?
Since each event is independent, the probability remains at 0.5.
You toss a coin 10 times what is the probability of getting heads 7 time?
7/10
What is the probability that they you will get two heads when you toss two coins?
If you toss them enough times, the probability is 1. For just one toss the probability is 1/4.
What is the experimental probability of getting tails on a coin toss after tossing it 100 times and getting tails 60 times?
It is 60/100 = 0.6
If you toss a coin 1000 times what is the probability of getting tales?
1 in 2
What is the probability of getting heads when you toss a coin ten times?
50% or 5
What is the probability of getting no heads when you toss a coin 4 times?
1 out of 16
If you toss a coin 1000 times and find that it comes up head 532 times what is the probability of getting a tail?
The probability is still 50%
What is the probability that they you will get two heads when you toss two coins?
If you toss them enough times, the probability is 1. For just one toss the probability is 1/4.
What is probability of getting 5 heads out of 8 times toss of a fair coin?
10 out of 32
You toss a coin 10 times what is the probability of getting heads 7 time?
7/10
Tossing a coin 9 times and getting tails what is the probability of getting tails on the next toss?
Since each event is independent, the probability remains at 0.5.
If you toss 4 coins what is the probability of getting four heads and zero tails?
The probability of getting a head is 1/2 and if you toss it 4 times, the probability of 4 heads is (1/2)^4=1/16 since the tosses are independent events.
What is the experimental probability of getting tails on a coin toss after tossing it 100 times and getting tails 60 times?
It is 60/100 = 0.6
What is the probablity that the sequence will be heads-heads-heads if you toss a coin 3 times?
the probability of getting heads-heads-heads if you toss a coin three times is 1 out of 9.
What is the probability of getting a head if coin is tossed 5 times?
The probability of getting a head on each occasion if a coin is tossed five times is equal to 1/2 x 1/2 x 1/2 x 1/2 x 1/2 (that is, 1/25) = 1/32 or one in thirty-two. The probability of getting a head on the fifth toss is 1/2. All other tosses are independent of the fifth toss. The probability of getting at least one head when tossing the coin 5 times: Since there are 32 possible combinations and only one of those combinations is all tails you could expect to toss a combination with a head 31/32 times. The probability is 0.96875.
