A soccer team estimates that they will score on 77% of the corner kicks. In next week's game, the team hopes to kick 1414 corn

andrezito [222]

Answer:

18.66521%

Step-by-step explanation:

It seems all of the numbers are duplicated, the correct number should be 7%, 14 corner kicks, and 2 opportunities.

The team has 7%(x=0.07) chance to score so that means the chance to not scoring will be: y= 1-x = 100%-7%= 93%. There are 14 opportunities and we want to know the probability to get exactly 2 scores. The calculation will be:

P(x=2)= 2C14 * x^2 * y^12

P(x=2)=91 * 0.07^2 * 0.93^12= 18.66521%
