Answer:

\frac{1}{9}

Step-by-step explanation:

Given :A spinner has three equal sections labeled 1, 2, and 3. It is spun twice.

Solution :Which expression can be used to determine P(2, then 1)?

Solution :

Total no. of events = {1,2,3}=3

When it is spin for the first time .

Since we are given in the first spin she should get 2

No. of Favorable events ={2}=1

probability of getting 2 = \frac{\text{No. of favorable events}}{\text{No. of total events}}

= 1/3

In second spin she should get 1

No. of Favorable events ={1}=1

probability of getting 1= \frac{\text{No. of favorable events}}{\text{No. of total events}}

=\frac{1}{3}

Thus  P(2, then 1) = \frac{1}{3} *\frac{1}{3}

Hence the expression : P(2, then 1) = \frac{1}{3} *\frac{1}{3}

                                                         = \frac{1}{9}

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
