Flip the coin three times and record your results. While we know the theoretical probability of flipping a heads, what is the ex
ivann1987 [24]

The probability of getting heads while flipping a coin for three times is 1/2

<u>Explanation:</u>

When a coin is flipped then there are two possible outcomes.

We can either get a heads or a tail.

If a coin is flipped three times and the possibility of getting heads would be 3

Total number of outcomes would be 6 ( 2 possible outcomes X 3 times toss)

Therefore, probability of getting heads would be = 3/6

                                                                                     = 1/2

Therefore, the probability of getting heads while flipping a coin for three times is 1/2

Answer:

Step-by-step explanation:

Things to remember:

1). When we divide a number having decimal by 10, 100, 1000 or any number multiple of ten, decimal point of the numerator shifts left by the number of zeros present in denominator.

Example:    \frac{2.0}{100}=0.02

2). When we multiply a decimal number by 10, 100, or any number number multiple of 10, decimal point of the original number shifts right by number of zeros present in multiplier.

Example:   2.0 × 100 = 200

In this question, 0.014 × 100000 = 1400.000

Therefore, product of 0.014 and 100000 is 1400 because the decimal point in 0.014 moves 5 places to the right.

0.45013 in scientific notation
Alik [6]
When putting numbers into scientific notation, always put the decimal after the ones place. In this case, you would put the decimal after 4 and before 5 (in between). From there, you count how many decimal places you moved in order to change it into that form.

0.45013 would change to 4.5013 and you would have to multiply it by 10 to the negative power of 1 (you're only moving back one place).

4.5013 x 10^-1

Hope this helps :)
