Sushil rolls a fair dice 138 times. How many times would Sushil expect to roll an even number

1 answer:

5 0

Since the chance of getting an even number on every roll is 3/6 or 1/2
We have to multiply 1/2 by 138

The answer is 69.

Hope this is correct, and pls correct me if I'm wrong :)

The answer is 0 because when you plug in the 3 and the 8 into the equation and do order of operations you will get 0.

To find the product of 42.12 and 10³, move the decimal point in 42.12 __ places to the right because 10³ has __ zeros.

<h3>To find the product of 42.12 and 10^3, move the decimal point in 42.12 3 places to the right because 10^3 has 3 zeros</h3>

<em><u>Solution:</u></em>

Given that,

$\text{ product of } 42.12 \text{ and } 10^3$

Which means,

$42.12 \times 10^3$

Here, the exponent of 10 is positive ( which is 3)

When the exponent is positive, we have to move the decimal point to right

When you multiply a number by a power of 10, ( 10!, 10^2, and so on ) move the decimal point of the number to the right the same number of places as the number of zeros in the power of 10

Here, exponent is 3 , therefore move the decimal point right 3 places in 42.12

Therefore,

$42.12 \times 10^3 = 42120$
