Exercise 1
when a car is brought to a repair shop for a service, the probability that it will need the transmission fluid replaced is 0.38, the probability that it will need the brake pads replaced is 0.28,
and the probability that it will need both the transmission fluid and the brake pads replaced is 0.16. let the event that a car needs the transmission fluid replaced be t and the event that
a car needs the brake pads replaced be
a. what are the values of the following probabilities?
i. p(t)
ii.
iii. p(t and
b. use the addition rule to find the probability that a randomly selected car needs the transmission fluid or the brake pads replaced.

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.
