Three resistors, with resistances R1,R2, and R3 are connected in series, R1 is normally distributed with a mean of 110Ω and a standard deviation of 15Ω,R2 is normally distributed with a mean of 135Ω and a standard deviation of 12Ω, and R3 is normally distributed with a mean of 120Ω and a standard deviation of 16Ω. What is the probability that total resistance (R1+R2+R3) exceeds 400Ω ?
given:Here, we are given that R1 follows a normal distribution with a mean of 110 and a standard distribution of 15. So, using standard notation we can write, R1 ~ N(110, 15^2)Similarly, we can write,R2 ~ N(135, 12^2)R3 ~ N(120, 16^2)
