It's the third option or C or 3

Answer:

THE ANSWER IS NOT C / 3

THE ANSWER IS "A"

Step-by-step explanation:

all the "hard" work is done (the numbers)...

lets start with the "units" at the end of the problem you have to have mm/day... so just start crossing out "top to bottom" when you see the same unit on the top and bottom... if you se day in the numerator and day in the denominator cross them out...

Do that and the one that has mm on the top and day on the bottom is the answer...

Step #2 ... two of the answers have that ... so now look for "silly fractions"

something like 1 year/ 999 days... your problem does not have totally silly things like that , but the WRONG answer has 1mm/ 10 cm (or something like that ) there is 10 mm in 1 cm, you choices has that opposit in one answer.

If an event has a 55% chance of happening in one trial, how do I determine the chances of it happening more than once in 4 trial

aev [14]

The chances of it happening more than once in 4 trials is 13%

<h3>How to determine the number</h3>

From the information given, we have can deduce that;

Probability of 1 trial = 55%

= 55/ 100

Find the ratio

= 0. 55

We are to find the probability of it happening more than once in 4 different trials

If the probability of it happening in one trial is 555 which equals 0. 55

Then the probability of it happening in 1 in 4 trials is given as;

P(1/4 trials) = 1/ 4 × 55%

P(1/4 trials) = 1/ 4 × 0. 55

Put in decimal form

P(1/4 trials) = 0. 25 × 0. 55

P(1/4 trials) = 0. 138

But we have to know the percentage

= 0. 138 × 100

Multiply the values, we have

= 13. 8 %

Thus, the chances of it happening more than once in 4 trials is 13%

Between 10 a.M. And 11 a.M., 48 people came into Brad's store. 40 of them made a purchase. What is the experimental probability

irina [24]

Answer: The required probability is $\dfrac{5}{6}$

Step-by-step explanation:

Since we have given that

Number of people came into Brad's store = 48

Number of them made a purchase = 40

So, the experimental probability that the next person to come into the store will make a purchase would be

$\dfrac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}\\\\=\dfrac{40}{48}\\\\=\dfrac{5}{6}$

Hence, the required probability is $\dfrac{5}{6}$
