1. When two coins are flipped simultaneously 24 times, on average 12 times we will get a head and a tail.

   For given question,

   When two coins are tossed simultaneously, the sample space is as follows:

   S = { HH, HT, TH, TT} where H denotes Head and T denotes tail.

   Using the formula of probability,

   P = Number of favorable outcomes/total number of outcomes,

   we get,

   P(HT) = 1/4

   and

   P(TH) = 1/4

   We know that the occurrence of two mutually exclusive events is the sum of their individual probabilities.

   So, P(Head on one and Tail on other)

   = P(HT) + P(TH)

   = 1/4 + 1/4

   = 2/4

   = 1/2

   = 0.5

   So, when two coins flipped simultaneously, the probability of flipping 2 coins and getting a head and a tail is 0.5

   In this question, we need to find the number of times getting a head and a tail when two coins are flipped simultaneously 24 times

   = 0.5 × 24

   = 12

   Therefore, When two coins are flipped simultaneously 24 times, on average 12 times we will get a head and a tail.
