Out of 124 students, only 31 students are taught to buy their lunches in the cafeteria.
<u>Step-by-step explanation:</u>
It is given that,
The 25% of 124 students are taught to buy their lunches in cafeteria.
Therefore, the total number of students taught to buy their lunches in cafeteria is 25% of 124.
<u>To find the number of students who are capable to buy lunches in cafeteria:</u>
- Replace the % symbol into the numeric form.
- The % is represented by 1 ÷ 100.
The 25% of 124 students is written as,
⇒ 25×(1/100)×124
⇒ (1/4)×124
⇒ 31
The number of students taught to buy lunches in the cafeteria out of 124 students is 31 students.
The probability of spinning a prime number and not flipping heads will be given as follows:
P(Prime)*P(Tails)
P(Prime)=3/5
P(Tails)=1/2
Thus
P(Prime) and P(Tails)
=3/5×1/2
=3/10
