Answer:
1/104
Step-by-step explanation:
Probability that the first card is a club = 1/4. (There are 13 club cards in the deck, and 13/52 = 1/4).
Probability that the second card is a 3 = 1/13. (There are four 3 cards in the deck, and 4/52 = 1/13).
Probability that the third card is red = 1/2. (There are 26 red cards in the deck, and 26/52 = 1/2).
Probability that the first card is a club, the second card is a 3, and the third card is red = 1/4 * 1/13 * 1/2
= 1/104
Answer:
La planta de la que ha salido el ascensor es: -1(planta del sótano)
Datos:

Answer:
Mean of 20 no.=18
Sum of 20 no.=20×18 i.e.360
When 2 is added to each no.,we get
360+(20×2)
=400
Now,new mean value of 20 no.=400÷20
=20
Step-by-step explanation:
You would find this as the only thing present was the isosceles triangle.
A + 2B = 180
A = 46
46 + 2B = 180
2B = 134
Now here's the tricky part. Just what are you being asked for? If it is both of the acute angles then the answer is 134°
If it is just one of them then the answer is 134/2 = 67°
I would take 67 because of the an. But what you have written is plural,which would make the answer 134.
