If you flip the five coins, and the probability of one coin being "tails" is 0.50, what is the probability of getting "tails" on

jenyasd209 [6]

Answer: 0.03125

Step-by-step explanation:

We know that the probability of getting a tail , we toss a fair coin = 0.5

Given : Total number of trials = 5

Using binomial probability formula :

$P(x)=^nC_xp^x(1-p)^{n-x}$ , where P(x) is the probability of getting success in x trails, n is total number of trials and p is the probability of getting success in each trial.

The probability of getting "tails" on all five coins :_

$P(x=5)=^5C_5(0.5)^5(1-0.5)^0=(1)(0.5)^5=0.03125$

Hence, the probability of getting "tails" on all five coins =0.03125

Rewrite –220° in radians. Write the solution as a fraction in simplest form.

son4ous [18]

Answer:

- $\frac{11\pi }{9}$

Step-by-step explanation:

To convert degrees to radians

radian measure = degree measure × $\frac{\pi }{180}$ , then

radian measure = - 220 × $\frac{\pi }{180}$ ( divide 220 and 180 by 20 )

= - $\frac{11\pi }{9}$
