What is the probability of rolling a 3 on two consecutive roll of a fair dice round your answer to the nearest hundred

do you want probability in fraction, percent, or decimal form?

Step-by-step explanation:

their is one 3 on a regular dice which has 6 numbers

this gives you the fraction 1/6

but since you are rolling the dice twice you would have 1/6 × 1/6 giving you 1/36

if in percent form this would be 2.77777778% or rounded to 3%

and decimal form as 0.0277777778 or rounded to 0.03%

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.
