We are given here that a blackjack hand consists of:
1 of the 4 aces = 4 / 52
1 of the 16 cards worth 10 points (10, jack, queen, king)
= 16 / 52
So assuming that cards are dealt without replacement,
therefore the probability of getting a blackjack hand is:
<span>P = 1st is ace * 2nd is 10 pt card +
1st is 10 pt card * 2nd is ace</span>
P = (4 / 52) * (16 / 51) + (16 / 52) * (4 / 51)
P = 0.04827 = 4.83%
Therefore there is a 4.83% probability to get a blackjack
hand.

The quadrilateral is a <u>parallelogram</u> because <u>both pairs of opposite sides</u> are parallel and since the product of the slopes of both pairs of <u>adjacent</u> segments is -1, the quadrilateral is a <u>rectangle</u>
Answer:
28 i tryed an this is wat i got so
Step-by-step explanation:
Answer:
angles 1 and 3 are 30
angles 5, 8, 10 and 12 are all 85
angle 11 is 95
angles 9 and 6 are 30
7 and 4 are 65
Step-by-step explanation:
angle 2 is congruent to 150, so 1 and 3 are: 360 degrees -150-150=x/2 to get the angles, then cos its an isosceles triangle due to the parallel lines, 9 and 6 are congruent to 1 and three, and 11 is 95 so you do 360 degrees-95-95=x/2 to get 85, then you take the 95 that is congruent to the angle group below it, and subtract 30 cos angles 9 and 4 are equivalent to the whole angle of 11, so yea u subtract 30 and you get 65, and you match up the congruent ones lol hope this helps ik its confusing
