givi [52]

1 day = 24 hours

130.91 hours  /  24 hours  = 5.45 days = 5.5 days

PLS HELLPPPP with a good and simplified explanation<br><br> just 7th grade.
umka21 [38]

Answer:

1 / 10 (1 : 10) (10%)  - your teacher has probably given you some idea as to the formatting of how you should write probability [so 3 different ways are written here], but I suspect they expect you to write it as 1 / 10

Step-by-step explanation:

only 1 out of all of these 10 trials is a "success" (aka what we are looking for)

we know that 7 matches the criteria of all years seeing a groundhog, and that all other options (1 , 2 , 3 , 4 , 5 , 6 , 8 , 9 , 10) do not meet this criteria.

so, the experimental probability** is 1 / 10 (or 1 : 10) (1 / 10 = 10%)

**: experimental probability is about how many times something happens in the experiment--not theoretically. it means that if his life was destined to be 1 of the 10, the probability of his experience matching the criteria is 1 / 10

experimental probability can be thought of as

successes / possible outcomes
