Challenge Suppose you have a bag with 50 letter tiles in it and 9 of the tiles are the letter T. If you 9
pick a letter tile at random from the bag, the probability that it is the letter T is
50
Suppose another
bag has 400 letter tiles in it and 168 of the tiles are the letter T. Write the probability of picking a tile
that is the letter T as a fraction and as a percent. From which bag are you more likely to pick a tile that
is the letter T?

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.
