on the weekly math test, there are 8 fraction problems, 4 addition problems, and 8 word problems. if malcolm misses one problem, what is the probability of missing a problem other than a word problem?\na. 4/20\nb. 5/20\nc. 8/20\nd. 12/20

on the weekly math test, there are 8 fraction problems, 4 addition problems, and 8 word problems. if malcolm misses one problem, what is the probability of missing a problem other than a word problem?\na. 4/20\nb. 5/20\nc. 8/20\nd. 12/20

Answer

Explanation:

Step1: Calculate total problems

$8 + 4+8=20$

Step2: Calculate non - word problems

$8 + 4 = 12$

Step3: Calculate probability

The probability $P=\frac{\text{Number of non - word problems}}{\text{Total number of problems}}=\frac{12}{20}$

Answer:

D. $\frac{12}{20}$
