Answer 1

tal: 1.___ Given that $25 $35 in in the the first hag second bag 3) f(x) = = = 0.46ex= 0 0.30, x= 95 0.94, X = 60 ca) Une E(X) = (0.30 *95) +(0.24*60) = 7.5 + 14.4 = $21.9 20%(95) ch) 0.94 *(609P1 E (x2) = . 10:30* (25) 10.94 :: 187.5 + 864 = $1051-5.

Variance = E(X²)-( E(X) = 10 51.5 - = 105 -5 -479.61 = $ 571-89. Standard deviation - Ivariance = 571.89 93914 (c) Average (140 * Mix) - (140 * 31:9). = $3066 Sl:- 2.
