Anumber cube is rolled 450 times. the number 3 comes up 67 times.

what is the experimental probability of rolling a 3? write your answer as a fraction in simplest form.

ok so i did this if i am right?

67/3 = 22.3
450/3 = 150

22.3/150 = ?
or
22/150 =

this where i get lost. i need a fraction. @whpalmer4 or @taz_kapadia or @tcarroll010

The probability that a u.s. resident has traveled to canada is 0.18 and to mexico is 0.09. a. if traveling to canada and traveling to mexico are independent events, what is the probability that a randomly-selected person has traveled to both? (page 109 in the book may ) b. it turns out that only 4% of u.s. residents have traveled to both countries. comparing this with your answer to part a, are the events independent? explain why or why not. (page 119 may ) c. using the %’s given, make a venn diagram to display this information. (don’t use your answer to part a.) d. using the conditional probability formula (page 114 in the book) and the %’s given, find the probability that a randomly-selected person has traveled to canada, if we know they have traveled to mexico.
