A box c_ontains 6 red balls and 2 blue balls. Ran_domly pick up 2 balls (one at a time) with replacement.

Question
A box c_ontains 6 red balls and 2 blue balls. Ran_domly pick up 2 balls (one at a time) with
replacement. (This me_ans that the first ball will be retur_ned to the box before picking up
another ball.) Suppose that, for each red ball, we win 1$ and b_ut for each blue ball, we lose
2$. Let X be the random var_iable representing the total amoun_t that we either win or lose
fro_m this ga_me. (Positive valu_es of X mean the total amou_nt that we w_in from the game, while
nega_tive valu_es of X mean the to_tal amo_unt we lose.).
- Find all possib_le values of X. (i.e, Find the
range sp_ace RX of X.) - Find and draw the gr_aph of the pro_bability mas_s
function (p.m.f) of X
