What is the probability of a blue jay being the next bird Lola sees?

A) 0.421
B) 0.042
C) 0.59
D) 0.059

Answer 1

59+68+12+1=139=Total # of birds or 100%
Blue Jays have been seen 59 times. That's 59 out of 140 or 59/140. 59/140 = 0.4214
Rounded to the nearest thousandth, 0.4214 is 0.421.
Your answer is A.
