140 birds in total 59 blue jays,68 black crows, 12 Red Robin’s and 1 cardinal what is the probability of the next bird being a blue jay

The probability of the next bird being a blue jay is 42.14%

Step-by-step explanation:

Given;

Total number of birds = 140

Number of blue jays = 59

Number of black crows = 68

Number of red robin's = 12

Number of cardinal = 1

The probability of the next bird being a blue jay is;

P = number of blue jay ÷ total number of birds

Substituting the values;

P = 59÷140

P = 0.4214

P = 42.14%

The probability of the next bird being a blue jay is 42.14%

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer

equal to
