In a gambling game a person draws a single card from an ordinary 52-card playing deck. A person is paid $17 for drawing a jack o

Artyom0805 [142]

Answer:

$E.G=\$2$

Step-by-step explanation:

Sample size 52 card

Pay for J or Q $=\$17$

Pay for King or Ace $=\$5$

Pay for others $=-\$2$

Therefore

Probability of drawing J or Q

$P(J&Q)=\frac{8}{52}$

Probability or drawing King or Ace

$P(K or A)=\frac{8}{52}$

Probability or drawing Other cards

$P(O)=\frac{36}{52}$

Therefore

Expected Gain is mathematically given as

$E.G=\sum_xP(x)$

$E.G=17*\frac{8}{52}+5*\frac{8}{52}+(-2)*\frac{36}{52}$

$E.G=\$2$

We see on the picture that :
When we go down one row, we add one horizontal and two diagonal cards.

In the first row we have 2 cards
In the second 2+3=5 cards
In the third 5+3=8 cards
etc.

General formula : in the n-th row from the top, we have $\boxed{ 2+(n-1)\cdot3\text{ cards}}$

3 is a factor of__ A)282 B)187 C)385 D)412

MrRissso [65]

Answer:

A. 282

Step-by-step explanation:

A trick I know is if you add all the digits of the number and they add up to a multiple of 3, it is divisible by 3.

282:

2 + 8 + 2 = 12

187:

1 + 8 + 7 = 16

385:

3 + 8 + 5 = 16

412:

4 + 1 + 2 = 7
