Abowler knocks down at least 6 pins 70 percent of the time. out of 200 rolls, how many times can you predict the bowler will knock down at least 6 pins

Multiply 200 rolls by 70%

200 *0.70 = 140

The bowler should knock at least 6 pins down 140 rolls

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)

the answer is 21%.
