<span>1) Find P(E1UE2)
E1 probability= 1/2</span>
<span>There are 26 red cards in a 52 card deck, so the probability of choosing a red card is = 26/52 = 1/2
E2 probability= 12/ 52 or 3/13</span>
<span>The face cards are: Jacks, Queens, and <span>Kings. There are four suits, so in each suit there are one jack, one queen and one king. The probability is 3 x 4= 12 divided by the total number of cards.
2)</span></span><span>the probability of drawing a blue ball on the first draw: 4 /10
</span>the probability of drawing a white ball on the second drawn: 6/9 (because there is less one ball from the previous draw).
the probability of the cases together is 4/15 ( 4 /10 x 6/9) <span>since they are independent cases.</span>
Answer:
x=4. Verified, Not wrong.
Step-by-step explanation:
24=9x+4-4x
24 = 5x+4
20-4
5x=20
(divide)
x=4
Answer:
y= 4x^2
Step-by-step explanation:
Answer:
0.004 km; 400 cm; 4000 mm
Step-by-step explanation:
1 km = 1000 m
1 = (1 km)/(1000 m)
4 m * (1 km)/(1000 m) = 4/1000 km = 0.004 km
1 m = 100 cm
1 = (100 cm)/(1 m)
4 m * (100 cm)/(1 m) = 400 cm
1 m = 1000 mm
1 = (1000 mm)/(1 m)
4 m * (1000 mm)/(1 m) = 4000 mm
Answer: 0.004 km; 400 cm; 4000 mm
