1. a factory makes bicycles. out of 300 bicycles, 2 were found to have defective brakes.

a. what is the experimental probability that the next bike manufactured will have defective brakes?

b. predict how many bikes out of 2,100 will have defective brakes.

* explain how you found the answers*

a. 1/150.

b. 14.

Step-by-step explanation:

a.  That would be 2/300 = 1/150.

b.  So we expect 1 out of every 150  bikes will have 1 with defective brakes so out of 2,100 it is (1/150) * 2,100

= 14.

your answer would be b

step-by-step explanation:

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
