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.
If you toss them enough times, the probability is 1. For just one toss the probability is 1/4.
you toss 3 coins what is the probability that you get exactly 2 heads given that you get at least one head?
Probability = 0.5
1 in 2 to get tails on first toss 1 in 2 to get heads on second toss To get tails on first toss and heads on second toss, probability is 1/2 x 1/2 = 1 in 4
the probability of getting heads-heads-heads if you toss a coin three times is 1 out of 9.
1/2 * 1/2 * 1/2 = 1/8 = 12.5%
The probability of heads is 1/2.
50% or 5
1 out of 16
It is 0.00540 approx.
