You are dealt one card from a​ 52-card deck. find the probability that you are not dealt a two
Rina8888 [55]

There are 52 cards in a deck.

First we find the probability of drawing a 2

There are 4 cards that shows 2

Probability of drawing a 2 card fro 52 cards = 4 / 52

We know that P( not A) = 1 - P(A)

So the probability (not dealt a 2) = 1 - probability (dealt a 2)

= 1 - 4/52

= (52 - 4)/ 52 = 48/52

Now we simplify the fraction

48/ 52 = 12/13

Hence, the probability( not dealt a 2) = 12/13

Rashid [163]
You have to do mutiplication. how do you know that you have to do mutiplcation because the (of) it means times. so  26 * 2.21 = 0.5746
         2.21/x=100/26
<span>(2.21/x)*x=(100/26)*x      </span>
<span>2.21=3.8461538461538*x      
</span>(3.8461538461538) to get x
<span>2.21/3.8461538461538=x </span>
<span>0.5746=x </span>
<span>x=0.5746</span>

Why is 296 divided by 6 equals 48 remainder 8
olya-2409 [2.1K]
Basically, 296 divided by 6 means 296 cut up into 6 parts
it doesn't divide equally into whole numbers so we have a remainder
we actually have a remainder of 2, not 8 since we have one 6 in 8 so  it actually is
296/6=49 remainder 2
