The probability that he gets fewer than 3 of them correct is : 0.80
<h3>Analysis of the problem </h3>
The problem is a Binomial problem
n = 8
P(correct ) = 1/5
<h3>Determine the probability that a student gets fewer than 3 correct answers </h3>
P( 0<= x <=2 ) = binomcdf ( 8, 1/5, 2)
= ⁸C₂(1/5)² (4/5)⁶ + ⁸C₁(1/5)(4/5)⁷ + ⁸C₀(4/5)⁸
= 0.7969 ≈ 0.80
Hence we can conclude that The probability that he gets fewer than 3 of them correct is : 0.80
