Good sir 😢😢 Please help me out random variable X has a probability mass function defined by 𝑃(𝑋 = 𝑥) = { 𝑘 (𝑥 − 1 ) , 𝑖𝑓 𝑥 = 2, 3 𝑘 ( 8 − 𝑥 ) , 𝑖𝑓 𝑥 = 4, 5, 6 0 𝑜𝑡ℎ𝑒𝑟𝑤𝑖𝑠𝑒 i) Write out the probability mass function of X. ii) Find the expectation of X. iii) Find the variance of X. iv) Find P(2 ≤ X ≤ 5) v) Find 𝑃(𝑋 ≥ 5)

I wish i can share it through your WhatsApp line please 🙏🙏🙏
