1. first we find how many defective capacitors are there out of 133, 450:

in         34       capacitors --------- 1 defective
in      133,450 capacitors --------- x defective

so x= \frac{133,450*1}{34}= 3925 is the expected number of defective capacitors.

2.

So there are in total 133,450-3925=129,525 working capacitors.

3.
To assemble 1,987 smartphones  the corporation needs 1,987*66= 131,142 working capacitors.

4. 
The number of required capacitors is larger than the number of the available ones, so 133,450 capacitors are not enough.

If the relative frequency of getting a red on a spinner is 0.4 how many reds would you expect to get in 300spins?
Sauron [17]

This relative frequency is an experimental probability:  that of getting a red on a spinner.  In 300 spins, we'd expect to get 0.4(300), or 120, reds.
