There are 35 marbles in a bag: 9 blue marbles, 8 green marbles, 4 red marbles, 8 white marbles, and 6 yellow marbles. Find P(red). Write the probability as a fraction in simplest form, a decimal, and a percent.
2. A number cube with the numbers 1 through 6 is rolled. Find P(number is greater than or equal to 3) Write as Fraction.
3. A multiple-choice question has five possible answers. What are the odds in favor of guessing the right answer? Write as Ratio.
FOr 1 i think 4/35 idk the rest
2. Pr(equal or greater than 3)=Pr(3)+pr(4)+pr(5)+pr(6)=4/6
for three ther is no choice for 1/5
sorry ms sue
Prob in favour of guessing right = 1/5
so the prob of NOT guessing right = 4/5
odds in favour of guessing right
= (1/5) / (4/5)
= 1/4 or 1 : 4
