Use the results of three card-game experiments in the table to find the theoretical probability of winning one hand of cards.

a. express your answer as a decimal.

b. explain how you know what to do to find your answer to one of your classmates who missed class.

experiment
1 2 3

number of hands: 30 50 200

number of wins: 9 15 46

a) o.3

b) use the theoretical probability therom:

# of favorable outcomes/#of possible outcomes

in this case it is 9/30=0.3

my answer the brainiest

Step-by-step explanation:

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1
