a) The probability that a transistor will last between 12 and 24 weeks is : P(12 < X <24) = F(24, 4, 6) - F(12, 4, 6) = F(24/6, 4) - F(12/6, 4) = F(4, 4) - F(2, 4) = 0.567 -0.143 = 0.424 Explanation: Using the formula, FOX: α; B) = F(x/B; 0)

Question
a) The probability that a transistor will last between 12 and 24 weeks is :
P(12 < X <24) = F(24, 4, 6) - F(12, 4, 6)
= F(24/6, 4) - F(12/6, 4)
= F(4, 4) - F(2, 4)
= 0.567 -0.143
= 0.424
Explanation:
Using the formula,
FOX: α; B) = F(x/B; 0)
