Answer:

\frac{9}{20}

Step-by-step explanation:

experimental probability is the probability of an event occuring when we perform an experiment.

It goes according to the results of the experiment, not the theory behind it.

<u>Probability of landing tails up, therefore, is the number of times it came tails up divided by the total number of times the coin was flipped.</u>

<u />

Hence

P (tails) = 36/80 = 9/20

I need help on this problem<br> 20 ÷ (4 - (10 - 8))
vlada-n [284]

Answer: 10

Explanation:

20 ÷ (4- (10-8))

First off, you work your way outward. You start the furthest in, then head your way out. (10 - 8) is the furthest in, and 10 - 8 = 2. So now your equation looks like this:

20  ÷ (4 - 2)

Next, you do the (4 - 2) which equals 2. So now, the equation is this:

20  ÷ 2

So you finish it up with 20  ÷ 2 which equals 10.

Hope I made sense! :D
