Step-by-step explanation:
Using the principle of probability, the likelihood that Shreya wins by getting <em>2 blues and 1 red</em> is 0.416
<u>Creating</u><u> </u><u>an</u><u> </u><u>area</u><u> </u><u>model</u><u> </u><u>for</u><u> </u><u>the</u><u> </u><u>first</u><u> </u><u>two</u><u> </u><u>spinners</u><u> </u><u>:</u>
___ G _ B _ B _ R _R _R
R_RG_RB_RB_RR_RR_RR
R_RG_RB_RB_RR_RR_RR
B_BG_BB_BB_BR_BR_BR
B_BG_BB_BB_BR_BR_BR
B_BG_BB_BB_BR_BR_BR
B_BG_BB_BB_BR_BR_BR
G_GG_GB_GB_GR_GR_GR
G_GG_GB_GB_GR_GR_GR
Creating an area model or tree diagram for the third spinner would result in a sample space of (48 × 12) = 576 combinations.
However, the probability that Shreya would win can be obtained thus :
<u>To win he needs to pick get 2 blues and 1 red</u> in any order :
3! = 3 × 2 × 1 = 6 ways
P(BBR) = 1/3 × 4/8 × 5/12 = 0.0694444
P(winning) = 6 × 0.0694444 = 0.416
Therefore, the probability that Shreya wins is 0.416.
