Eva wants to know the probability of tossing heads at least three times out of five she used the random number table to simulate flipping a coin she assigned odd digits to represent heads and even digits to represent tails

use the table to find p("heads" at least 3 out of 5 times)

• 3/8
• 7/8
• 5/16
• 13/16

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.
