Question

7(b) Maria is playing a game on her smartphone. She will choose an image to see if she gets bonus points. The probability of getting bonus points is16Find the odds in favor of getting bonus points.0:0 toX?

Answer 1

First, let's remember the following definition.

• The ,odds, are the ratios that compare the number of ways the event can occur with the number of ways the event cannot occur.

• The ,odds in favour, = the ratio of the number of ways that an outcome can occur compared to how many ways it cannot occur.

• Odds ,in favour, = Number of successes : Number of failures

From the statement of the problem, we know that the probability of getting bonus points is P = 7/16. That means that we have:

• Number of successes = 7,

,

• Number of failures = 16 - 7 = 9.

So the odds in favour of getting bonus points are: 7:9

Answer: 7:9
