A box of candy hearts contains 52 hearts, of which 19 are white, 10 are tan, 7 are pink, 3 are purple, 5 are yellow, 2 are orang

laiz [17]

<u>Answer-</u>

a. Probability that three of the candies are white = 0.29

b. Probability that three are white, 2 are tan, 1 is pink, 1 is yellow, and 2 are green = 0.006

<u>Solution-</u>

There are 19 white candies, out off which we have to choose 3.

The number of ways we can do the same process =

$\binom{19}{3} = \frac{19!}{3!16!} = 969$

As we have to draw total of 9 candies, after 3 white candies we left with 9-3 = 6, candies. And those 6 candies have to be selected from 52-19 = 33 candies, (as we are drawing candies other than white, so it is subtracted)

And this process can be done in,

$\binom{33}{6} = \frac{33!}{6!27!} =1107568$

So total number of selection = (969)×(1107568) = 1073233392

Drawing 9 candies out of 52 candies,

$\binom{52}{9} = \frac{52!}{9!43!} = 3679075400$

∴P(3 white candies) = $\frac{1073233392}{3679075400} =0.29$

Total number of ways of selecting 3 whites, 2 are tans, 1 is pink, 1 is yellow, and 2 are greens is,

$\binom{19}{3} \binom{10}{2} \binom{7}{1} \binom{5}{1} \binom{6}{2}$

$=(\frac{19!}{3!16!}) (\frac{10!}{2!8!}) (\frac{7!}{1!6}) (\frac{5!}{1!4!}) (\frac{6!}{2!4!})$

$=(969)(45)(7)(5)(15)=22892625$

Total number of selection = 3 whites + 2 are tans + 1 is pink + 1 is yellow + 2 greens = 9 candies out of 52 candies is,

$\binom{52}{9}=\frac{52!}{9!43!} =3679075400$

∴ P( 3 whites, 2 are tans, 1 is pink, 1 is yellow, 2 greens) =

$\frac{22892625}{3679075400} = 0.006$

A deli sells a sandwich spread for 6.4per pound. How much do you need to pay for 24 ounces of spread?

Dafna1 [17]

Answer:

You have to pay 9.6.

Step-by-step explanation:

In order to find the answer, first you have to consider that 1 pound is equal to 16 ounces and with that information, you can use a rule of three to find the pounds that 24 ounces represent:

1 pound → 16 ounces

x ← 24 ounces

=(24*1)/16=1.5

Now that you know, that 24 ounces are equal to 1.5 pounds you can multiply the price per pound for the number of pounds to find the amount that you need to pay:

6.4*1.5=9.6

According to this, the answer is that you have to pay 9.6.

Shikha deposited Rs 2000 in a bank which pays 6% simple interest. She withdrew Rs 700 at the end of the first year. What will be

grandymaker [24]

Rate of interest is given as 6% and Principle amount as Rs2000
Interest after 1 year= P*R*T/100 = 2000*6*1/100 = Rs 120
Net amount at the end of first year= Principle+ interest-Amount withdrawn=2000+120-700= Rs 1420
For the next 2 years, simple interest will be paid at the rate of 6% on the amount of Rs 1420 which is = 1420*6*2/100 =Rs 170.40
Balance after 3 years= 1420+170.40=Rs 1590.40
