The number of races the team need to win today for the team to have a 75% success rate is 15
Number of attempt = 45
Number of winnings = 30
Percentage won so far = 30/45 × 100
= 66.67%
let
x = Number of races that tfe team needs to win to have 75% success rate
(30 + x) / (45 + x) = 0.75
Cross product
30 + x = 0.75(45 + x)
30 + x = 33.75 + 0.75x
x - 0.75x = 33.75 - 30
0.25x = 3.75
x = 3.75 / 0.25
x = 15
Therefore, the number of races the team need to win today for the team to have a 75% success rate is 15
