1. The forthcoming verisimilitude division represents the estimate of nation subsistence in a Well-acquainted (X), and the verisimilitude of transaction (P(X)). Value the Expected Value (mean), the Variance and the Standard Deviation for this vague inconstant.     X       1         2        3          4          5                  P(X)    .34      .29      .18        .12       .07         2. Use the binomial formula to value the verisimilitude of a novice getting 4 amend replys on a 9 inquiry Quiz, if the verisimilitude of echoing any one inquiry amendly is 0.77. SHOW YOUR WORK. 3. Submit your replys to the forthcoming binomial inquirys. You may use the appendix tables 5 to reply cleverness a and b. According to a council examine,15% of all offspring speed in a well-acquainted that has an proceeds under the destitution raze. If a vague illustration of 20 offspring is selected: a) what is the verisimilitude that 4 or past speed in destitution? b) what is the verisimilitude that 4 speed in destitution? c) what is the expected estimate (mean) that speed in destitution?
