Step-by-step explanation:

Given

Represent loose threads with L, Crooked stitching with C.

So, we have:

Required

Calculate P(L or C)

In probability:

In this case:

Substitute values for P(L), P(C) and P(L and C)

Convert to decimal

Hence:

The required probability is 0.13

answer: 20

step-by-step explanation:

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315
