Binomial experiments are ruled by a very clean formula: if you want k successes performing n experiments with probability of success p, the probability is
If you plug your values, you'll get
Answer:
r = 5.4
Step-by-step explanation:
Formula:
P = πr + 2r
27.756 = πr + 2r
27.756 = 3.14r + 2r
27.756 = 5.14r
r = 5.4
1+1=2
