statistics and probabilities
posted by rhinechilde .
Suppose you will be taking exams in English, statistics and chemistry tomorrow and from past experience you know that for each exam you have a 50% chance of receiving an A. List all the possibilities for receiving A's on various exams. Letting X represents the number of A's you'll expect to receive, shows the distribution of X, that is, the values and associated probabilities. kindly help me with this...thanks.
