Dan and Brian have played 51 tennis matches. Dan has won 29 times.
Brian won the rest.
a) Estimate the probability that Dan wins.
b) Estimate the probability that Brian wins.

A = 29/51   B = 22/51

Step-by-step explanation:

(E) =  number of favorable outcomes/ total number of possible outcomes

- number of possible outcomes= 51

- number of favorable outcomes= 29

therefore, P(E) = 29/51

- number of possible outcomes= 51

- number of favourable outcomes = 51 - 29 = 22

therefore, P(E)= 22/51

2/3

step-by-step explanation:

the slope of a line is equal to the rise/run. in this case the line rises 2 units for every +3 units it moves

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
