If both spinners are spun simultaneously, what is the probability that both spinners will land on red? 2/64 1/8 2/8 3/64

spinner one

1 red/ 8 possible  = 1/8

spinner two

1 red / 8 possible  = 2/8

now multiple both

1/8 x 2/8  = 2/64

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)
