The probability of the students to be randomly selected between 350 and 550 will be 0.2395 or 24%
<h3>What will be the probability? </h3>
we know that the formula for probability is given by
where,
Z = Z score,
X = raw score,
μ = mean,
σ = standard deviation,
The probability of the students to be selected randomly between 350 and 550 will be given as
Thus the probability of the students to be randomly selected between 350 and 550 will be 0.2395 or 24%
