Mathematics: Rhonda is playing a board game. the players take turns rolling a pair of number cubes. on her next turn rhonda must roll a 5 to win the game, but if she rolls a double she gets an extra turn. a. explain why the events rolling a 5 and rolling doubles are mutually exclusive. b. if the probability of rolling a 5 is 1/9 and the probability of rolling doubles is 1/6, what is the probability that rhonda rolls either a 5 or doubles on her next turn. express your answer as a fraction in simplest form.

Step-by-step explanation:Right triangle ABC is reflected over AC to form triangle AFC.Triangle AFC dilated by a scale factor of two-thirds to form triangle DEC.Reflection is a rigid transformation which preserves lengths and angles, then Dilation is a transformation which maps the triangle into similar triangle, soThus,Similar triangle have congruent corresponding angles, soand proportional corresponding sidesThus, correct options are:...

A) We presume "roll a 5" means rolling the dice so they come up with a total of 5 spots on top. 5 is not an even number, so when 5 is showing, the numbers on the two dice must be different, hence cannot be doubles.

b) Since these events are mutually exclusive, we can simply add their probabilities: (1/9) +(1/6) = 2/18 +3/18 = 5/18.
