here are two misshapen coins in a box; their probabilities for landing on heads when they are flipped are, espectively, 0.4 and 0.7. One of the coins is to be randomly chosen and flipped 9 times. Given that two of the first ree flips landed on heads, what is the conditional expected number of heads in the 9 flips? The conditional expected number of heads in the 9 flips is Round to three decimal places as needed.)
