What is the probability that a family of 4 children will have all girls?

1 answer:

3 0

Since as of now we're saying that the probability of having a girl is 1/2, we can say:
1/2 * 1/2 * 1/2 * 1/2, because then you're saying a one half chance of having a girl times another one half chance of having a girl, etc.
That ends up to be 1/16.

Aiden borrows a book from a public library. He read a few pages on day one. On day two, he reads twice the number of pages than

Fofino [41]

Let the number of pages read on day 1 be = x

Then on day 2 he read twice the pages from day one, it is = 2x

On 3rd day he read 6 pages less than 1st day, it is = x-6

Total pages are = 458

The equation becomes: $x+2x+x-6=458$

$4x-6=458$

$4x=464$

$x=116$

So on the third day, Aiden read $x-6=116-6=110$ pages.

jenny wants to buy a winter coat for $200. the store advertises that customers can take 25% off the original price and then take

777dan777 [17]

Hello!

Let's check:

200 * 25% = 50

200 - 50 = 150

150 * 10% = 15

150 - 15 = 135

So, with the 25% and then an extra 10% off, the coat would cost $135.

200 * 35% = 70

200 - 70 = 130

So, Jenny's friend is incorrect, because that is not the same as a 35% discount.
