A store is selling 5 types of hard candies: cherry, strawberry, orange, lemon and pineapple. How many ways are there to choose:(

Volgvan

Answer:

The number of ways of selecting of n items form r different items = $^{(n+r-1)}C_{(r-1)}$

A store is selling 5 types of hard candies: cherry, strawberry, orange, lemon and pineapple.

A) How many ways are there to choose 32 candies?

So, n = no. of items = 32

r = no. of types of items = 5

So, No. of ways to choose 32 candies = $^{(32+5-1)}C_{(5-1)}$

= $^{36}C_{4}$

= $\frac{36!}{4!(36-4)!}$

= $58905$

So, No. of ways to choose 32 candies is 58905

B)32 candies with at least a piece of each flavor?

Out of 32 you choose 5 candies of different types

So, Remaining candies = 32 - 5 = 27

So, No. of ways to choose 27 candies = $^{(27+5-1)}C_{(5-1)}$

= $^{31}C_{4}$

= $\frac{31!}{4!(31-4)!}$

= $31465$

So, No. of ways to choose 32 candies with at least a piece of each flavor is 31465

C) 32 candies with at least 4 cherry and at least 6 lemon?

So, you already choose 6+4= 10

So, remaining candies = 32-10 = 22

So, No. of ways to choose 22 candies = $^{(22+5-1)}C_{(5-1)}$

= $^{26}C_{4}$

= $\frac{26!}{4!(26-4)!}$

= $14950$

Hence No. of ways to choose 32 candies with at least 4 cherry and at least 6 lemon is 14950

Use the order of operations to simplify the expression. 4[3+3(5-1)] What is the answer?

Nitella [24]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{60}}}}}$

Step-by-step explanation:

Using PEMDAS rule

Parentheses, Exponents , Multiplication, Division, Addition, Subtraction

$\sf{4 [ 3 + 3(5 - 1) ]}$

Subtract 1 from 5

$\longrightarrow{ \sf{4 [3 + 3 \times 4 ]}}$

Multiply the numbers : 3 and 4

$\longrightarrow{ \sf{4 [ 3 + 12 ]}}$

Add the numbers : 3 and 12

$\longrightarrow{ \sf{4 \times 15}}$

Multiply the numbers : 4 and 15

$\longrightarrow{ \sf{60}}$

Hope I helped!

Best regards! :D
