Question

In a school, only 3 out of 5 students can participate in a competition. What is the probability of the students who do not make it to the competition?(a) 0.65 (b) 0.4(c) 0.45(d) 0.6

Answer 1

Answer:

P(students not participating in competition)=2/5=0.4

Answer 2

$Probability \: of \: students \: participating$

$in \: a \: competition = \frac{3}{5}$

$Probability \: of \: students \:not\: participating$

$in \: a \: competition = 1- \frac{3}{5}$

$= \frac{5-3}{5}$

$= \frac{2}{5}$

$= 0.4$

Therefore.,

$Option \: \pink{ ( b ) } \: is \: correct.$
