Answer:
Total possible number of outcomes = C(24,6) [24 choose 6]
=24!/(6!18!)
= 134596
Out of which there is only one winning combination.
Therefore we conclude:
P(win 20000)=1/134596
P(lose 1)=134595/134596
and hence the expected value is:
20000*(1/134596)+(-1)*(134595/134596)
=-114595/134596
=-0.8514 (rounded to four places after decimal)

Place value of 4 is 4/100
Answer:
The third one and the fourth one.
Step-by-step explanation:
61 x 5 = 305. Not 3050
381*27=10287. Not 1152
854*63=53802.
562*42=23604
72*30=2160. Not 270
If there are choices, then you need to choose the correct choice, but if there are no choices, then one correct answer is to multiply the first equation by -2 and add it to the second equation to eliminate x and solve for y.
