a) P(3) = $\frac{11}{100}$ (or 0.11 or 11%)

b) Number of sixes = P(6) x 500

= $\frac{12}{100}$ x 500

= 12 x 5

= 60

if one card is drawn from a standard 52 card playing deck, determine the probability of getting a ten, a king or a diamond.

IceJOKER [234]

To find the answer:

The probability of getting a ten:

=4/52

The probability of getting a king:

=4/52

The probability of getting a diamond:

=52×1/4
=13/52

However,there would be king and ten of diamond which overlapped and therefore -2/52 would be in the equation.

We can then sum up to find the equation:

=4/52+4/52+13/52-2/52
=21/52-2/52
=19/52

Therefore the answer is 19/52.

Hope it helps!

While shopping, Dawn finds a backpack that she likes on the sale rack. Its original price is $60,

Nadya [2.5K]

No. Because 33 $ is the money deducted from the 60 $. Dawn bought everything for less than 60 $.

So, if Dawn purchases everything on the rack with a 30% discount and 15% coupon the total will indeed make 45%.

We have to take 100% - 45%= 55% to know the reduction number. Let's proceed to the calculations now.

100%= 60 $

1%=60/100

55%= 60/100 × 55 = 33 $

Now NOTE; 33 $ is the money reduced from the 60 $. So, logically, 33 $ isn't the amount which Dawn purchased the whole rack. 

To find the amount at which she purchased everything, we need to do,

60 $ - 33 $ = 27 $
