P = 10% = 0.1
q = 1 - 0.1 = 0.9
P(at least one defective calculator) = P(1) + P(2) + P(3) + P(4) = 1 - P(0)
The brobability of a binomial distribution is given by
where: n = 4
Therefore,
P(at least one defective calculator) = 1 - 0.6561 = 0.3439

<u>Answer-</u>
<u>Solution-</u>
As we know that, on the number line, if a number is on the right of another number, then the former number is greater than the later number.
As, the number on the right side are 4, 5, ...so on (4 is dotted so it is included)
So the inequality will be
As, the number on the left side are -3, -4, -5, ..... so on (-2 is not dotted so it is excluded)
So the inequality will be
Then the compound inequality will be,
