Answer:
Part B
Hope you don't need explanation :)
<span>There are 2 drawings, in the 1st one we have
to select correct four numbers between 1 and 62 while the 2nd one is
to select the one single number between 1 and 16.</span>
<span>In the 1st drawing, the probability of success
is 1 divided by the total number of 4 combinations that can be created from 62
numbers.</span>
P1 = 1 / 62C4
P1 = 1 / 557,845
<span>In the 2nd drawing, the probability of success
is 1 divided by 16:</span>
P2 = 1 / 16
Since the two drawings must be satisfied before you can
win the jackpot, then multiply the two:
P = P1 * P2
P = (1 / 557,845) (1 / 16)
P = 1 / 8,925,520 = 1.12 x 10^-7 = 1.12 x 10^-5 %
<span>Therefore the odd in winning this lottery is 1 in 8,925,520
chances.</span>
Easy, so absolute value makes anything inside into positive
|x|=2
therefor x=-2 or x=2 since it would be made posotive
answer is -2 and 2
