In 7-card poker, played with a standard 52-card deck, 52C7, or 133,784,560, different hands are possible. The probability of being dealt various hands is the number of different ways they can occur divided by 133,784,560.
Shown to the right is the number of ways a particular type of hand can occur and its associated probability. Find
the probability of not being dealt this type of hand.

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
