Suppose the child is still asked to choose between a blue or red crayon but is now offered 3 picture choices: balloon star or box use a tree diagram to determine the probability of each outcome
1.find p ( red, box)
2.find p (red, star)
3.find p (blue, not star)
4.find p (blue, balloon)
5.find p (not blue, not balloon)
6.find p (blue or red, box)
7.find p (red, any picture)

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.
