help me understand coing toss probability. Question: if you flip a coin 15 times, how many tails do you expect them to get? so i know basically 50% chance it's head or tails and the outcome for 15 coin flips is 2 to the 15th power which comes out to be 32,768. How do I solve this though? help thank you
