You can do part a using The Pythagoras theorem:-

30^2 = x^2 + 24^2

x^2 = 30^2 - 14^2 = (30+24)(30-24) = 324

x = 18

The table shows the number of championships won by the baseball and softball leagues of three youth baseball divisions organized

Scrat [10]

Answer:

0.5 or 50%

Step-by-step explanation:

Total number of championships won = 3+2+1+7+2+1=16
Total Number of winners in baseball league, n(B)= 3+2+1=6
Number of Wins in the Ages 10 - 12 division, n(Y) =2
Number of Wins in the Ages 13-15 division, n(Z) =1

The probability that the winning team is in the Ages 10 - 12 division given that it is in the baseball league:

$P(Y|B)=\dfrac{P(Y \cap B)}{P(B)} \\=\dfrac{2/16}{6/16}\\=\dfrac{2}{6}$

The probability that the winning team is in the Ages 13 - 15 division given that it is in the baseball league:

$P(Z|B)=\dfrac{P(Z \cap B)}{P(B)} \\=\dfrac{1/16}{6/16}\\=\dfrac{1}{6}$

Therefore:

$P(Y$ or $Z|B)=\dfrac{2}{6}+\dfrac{1}{6}\\=\dfrac{3}{6}\\\\=0.5$
