Answer 1
Answer:  0.85  (Choice A)

===========================================================

Explanation:

x = number of siblings

We add the probability values that correspond to x = 0 and x = 1, which is when the person has 0 siblings and 1 sibling respectively.

Those probabilities are: 0.20 and 0.65

So we get 0.20+0.65 = 0.85

There's an 85% chance of randomly picking someone who has fewer than two siblings.

Answers

Answer:

[tex]average \ score \ of \ Mari = \frac{72+80+90+73+74+90}{6} = 79.83\\average \ score \ of \ Kai = \frac{56+63+70+100+32+23}{6} = 57.33\\[/tex]

The next test they both score 100

[tex]average \ score \ of Mari = \frac{72+80+90+73+74+90+100}{7} = 82.71\\average \ score \ of Kai = \frac{56+63+70+100+32+23+100}{7} = 63.43\\[/tex]

The increase in average score for Mari is 82.71 - 79.83 =2.88

The increase in average score for Kai is 63.43 - 57.33 = 6.1
