The probability of getting a 1 is 0.3
krek1111 [17]

Answer: 45

Step-by-step explanation:

\\To calculate the probability of the number of times a 1 we appear , we have

\\number of times a 1 appeared / Total number of times the die is rolled.

\\Let x represent the number of times a 1 is gotten

\\And we have been given the probability of getting a 1 and also the total number of times the die is being rolled , substituting this inside the formula above , we have

\\0.3 =  x / 150

\\x = 150 x 0.3

\\x = 45

Use the table of reciprocals to find the reciprocal of these numbers:<br> 0.000 080 25 <br> 0.9596
Licemer1 [7]

Answer:

1000000/8025 = 40000/321 (simplified)

1000/9596

Step-by-step explanation:

Hi there,

There is an alternative way to do this....

First it is important to understand what a reciprocal is. The reciprocal of any number x is the number 1/x. The reciprocal of a number is also its multiplicative inverse, which means that the number times its reciprocal must equal 1. For a number such as 2, the reciprocal would be 1/2. For a fraction such as 2/5, the reciprocal would be 5/2.

Finding the reciprocal of a decimal can be done in a number of ways.

Change the decimal to a fraction first.

Ex. 0.25 is 25/100 and is equivalent to the fraction 1/4. Therefore Its reciprocal would be 4/1 or 4.

Keep the decimal and form the fraction 1/?? which can then be or converted to a decimal.

Ex. 0.75 The reciprocal is 1/0.75. Using a calculator, the decimal form can be found by performing the operation: 1 divided by 0.75. The decimal reciprocal in this case is a repeating decimal, 1.33333....

After finding a reciprocal of a number, perform a quick check by multiplying your original number and the reciprocal to determine that the product is 1:

(0.25)(4) = 1.00

(0.75)(1.33....) = 1 but it is easier to see for sure with repeating decimals if you use the fractions instead of the decimals.

(3/4)(4/3) = 12/12 = 1

Hope this helps, Mark as brainliest if liked it! thanks!
