Layla has a coin that has a 60\%60%60, percent chance of showing heads each time it is flipped. She is going to flip the coin 55
valina [46]

The probability that she gets <em>more than 3 heads</em> is 0.3456.

There are only two possible outcomes for a fliped coin, either it is head, or it is tail. Since the result is independent of each other coins, the binomial distribution will be used.

Given the following parameters:  

  • x is the number of successes = 5 (coin flipped 5 times)
  • n is the number of trials
  • p is the probability of success on a single trial = 0.6

Using the binomial distribution formula:

P(X =x)=nC_x p^x (1-p)^{n-x}\\P(X =3) = 5C_3 \ (0.6)^3 (1-0.6)^{5-3}\\P(X =3) = 5C_3 \ (0.6)^3 (0.4)^{2}\\P(X=3)=0.3456

Hence the probability that she gets <em>more than 3 heads</em> is 0.3456.
