A card is selected at random from a well-shuffled ordinary deck consisting of 13 spades, 13 clubs, 13 hearts, and 13 diamonds. 4
Elis [28]

Answer:

b) 0.42

Step-by-step explanation:

Let A be the event that card is a heart card and B be the event that card is a face card.

We have to find P(A or B). P(A∪B)=?

P(A∪B)=P(A)+P(B)-P(A∩B)

There are 13 heart cards and  12 cards are face cards. There would be 3 face card in hearts. So,

P(A)=13/52=1/4=0.25

P(B)=12/52=3/13=0.231

P(A∩B)=3/52=0.058

P(A∪B)=0.25+0.231-0.058

P(A∪B)=0.481-0.058

P(A∪B)=0.423

So, the probability that the card is a heart or is a face card is about is 0.42.

What is the 214 term in the sequence 7,10,13,16?
mixer [17]
We can figure this out using the explicit formula.

f(n)=f(1)+d(n-1)

n represents the term we are looking for.
f(1) represents the first term in the sequence, which in this case, is 7.
d represents the common difference, which in this case, is +3.

f(n) = 7 + 3(n - 1)
f(n) = 7 + 3n - 3
f(n) = 4 + 3n

Now, we can input 214 for n and solve.

f(214) = 4 + 3(214)
f(214) = 4 + 642
f(214) = 646

The 214th term in this sequence is 646.
