Enter your answers in this order: reduced fraction,decimal, and then percent.P(B)2/10(reduced fraction) =1/5(decimal) =20This is an example of experimental probability.How many outcomes are in the sample space? OutcomesIn this case, choosing a baseball is theWhat is the probability of pulling out a tennis ball?P(T) =(reduced fraction) =(decimal) =%.Which is more likely to occur?tennisWhy? Because the probability is closer to 1Please answer all parts of the question.

Mitchell is getting ready to take a baseball rules exam in order to becomne certified as a baseball umnpire in his local community. Past scores on the rules exam form a normal distribution with u = 80 and o = 6. Mitchell must score in the highest 25% of the distribution in order to become a certified umpire. Which minimum score does Mitchell need to obtain on the rules exam to become a certified umpire? OX= 76 O X- 84 OX= 86 OX-81
