How to solve a probability problem
WebProbability is the likelihood of an event occurring. To find the probability of an event happening we use the formula \text {Probability}=\frac {\text {number of desired outcomes}} {\text {total number of outcomes}} Probability = total number of outcomesnumber of desired outcomes For example, WebThe variable Y can take values 0' — 15 and C — 15 — 1000 and has the following probability distribution 2 P(Y = 0— 15— 1000) 2 Ho = 0.02 2 PY=C—15 =1——=0.98 ( ) 100 We want to know how much should the company charge for the policy if it requires that the expected profit per policy be 50.

WebFeb 15, 2024 · The grand total is the number of outcomes for the denominator. Consequently, to calculate joint probabilities in a contingency table, take each cell count and divide by the grand total. For our example, the joint probability of females buying Macs equals the value in that cell (87) divided by the grand total (223).
