a certain spinner has equally sized slices. The odds in favor of landing on a blue slice are 2:5.What is the probablility of landing on a blue slice?

prob of landing on blue = 2/7

3/5

To find the probability of landing on a blue slice, we need to calculate the ratio of favorable outcomes to total outcomes.

Given that the odds in favor of landing on a blue slice are 2:5, this means that out of a total of 7 equal slices, there are 2 slices that are blue and 5 slices that are not blue.

Therefore, the probability of landing on a blue slice can be calculated as:

Probability of landing on a blue slice = Number of favorable outcomes / Total number of outcomes
= 2 / 7

So, the probability of landing on a blue slice is 2/7.

To find the probability of landing on a blue slice, we need to divide the number of favorable outcomes (blue slices) by the total number of possible outcomes (all slices on the spinner).

Given that the odds in favor of landing on a blue slice are 2:5, this means that out of every 2 + 5 = 7 equal-sized slices, 2 of them are blue.

So, the probability of landing on a blue slice is 2/7 or approximately 0.286 (rounded to three decimal places).
