Four tiles lettered H, O, P, and E are face down on a table. A tile is selected, the letter recorded, the tile replaced, and the process is repeated. What is the experimental probability of selecting an H? The results are H-5, O-5, P-4, E-6.

1/4

Step-by-step explanation:

Given that :

Result obtained : H-5, O-5, P-4, E-6

Hence, number of trials = (5 + 5 + 4 + 6) = 20

Experimental probability :

(Number of occurences of an event / total number of trials)

Experimental probability of selecting an H;

Number of occurrences of H = 5

Total number of trials = 20

P(selecting an H) = 5/20

= 1/4

Hence, the experimental probability of selecting an H is 1/4

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
