If a coin is flipped 75 times, in how many ways could there be exactly two tails?

Dimas [21]

Answer:

2775 ways

Step-by-step explanation:

We have been given the case to choose exactly two tails when flipped 75 times means $^{75}C_2$

Since, $^nC_r$ is equal to $\frac{n!}{r!\cdot(n-r)!}$

Here n =75, r=2 substituting the values we will get

$\frac{75!}{2!(75-2)!}$

$n!=n\cdot (n-1)\cdot (n-2).....1$

After simplification we will get $\frac{75\cdot 74\cdot 73!}{2!\cdot73!}$

Cancel out the common term that is 73! we will get

after more simplification we will get $\frac{75\cdot 74\cdot}{2!}$

Finally, we will get $\frac{75\cdot 74\cdot}{2}=75\cdot37=2775$

The price of an item has been reduced by 30%. The original price was $70. What is the price of the item now?

Jlenok [28]

Answer:

$41.25

Step-by-step explanation:

We can use this formula to solve this problem:

s

=

p

−

(

d

×

p

)

Where:

s

is the sales price: what we are solving for in this problem.

p

is the original price: $55 for this problem.

d

is the discount rate: 25% for this problem. "Percent" or "%" means "out of 100" or "per 100", Therefore 25% can be written as

25

100

.

Substituting and calculating

s

gives:

s

=

)

s
