Mickey tosses a coin 50 times and records 27 heads. Based on these results, what is the probability if
JulijaS [17]

The probability of getting three tails in three tosses When Mickey tosses a coin 50 times and records 27 heads is 12,167:125,000.

<h3>What is probability of an event?</h3>

It is the ratio in an event of the number of favorable outcome to the total number of outcome of that event.

As the probability of an event can not be more than the number 1. Thus, he probability of failure of a event is equal to the difference of the 1 to the success of the event.

Mickey tosses a coin 50 times and records 27 heads. Thus, the probability of getting a head is,

P=\dfrac{27}{50}\\

The probability of not getting a head or getting a tail is,

P^{-1}=1-\dfrac{27}{50}\\P^{-1}=\dfrac{50-27}{50}\\P^{-1}=\dfrac{23}{50}

Now, Mickey tosses the same coin three more times. The probability of getting three tails in these tosses are,

P_{3t}=\dfrac{23}{50}\times\dfrac{23}{50}\times\dfrac{23}{50}\\P_{3t}=\dfrac{12167}{125000}

Thus, the probability of getting three tails in three tosses When Mickey tosses a coin 50 times and records 27 heads is 12,167:125,000.

Vitek1552 [10]

Answer:

x=48

Step-by-step explanation:

10x-20+6x+8=180 set the equations together and to equal 180 since a line is 180 degrees

Get the variables together

10x-20+6x+8=180

-6x       -6x

4x-20+8=180

add together -20 and 8

4x-12=180

add -12 on each side

4x-12=180

   +12  +12

4x=192

divide all by 4

x=48

LU 1<br>- 2x + 3 &lt; 5 and - 4x – 3 &gt; 9​
Lynna [10]

Answer: x>-1

               x<-3

Step-by-step explanation:

-2x+3

subtract 3 on both sides

-2x

divide -2 on both sides

x>-1

The sign changed because I divided by a negative.

-4x-3>9

add 3 on both sides

-4x>12

multiply -1 on both sides

4x

divide 4 on both sides

x
