Answer:
 16/29
Step-by-step explanation:
P(A∪B) = P(A) + P(B) - P(A∩B)
P(basketball or baseball) = P(basketball) + P(baseball) - P(both)
 = (13/29) + (7/29) - (4/29)
 = 16/29
The probability that a randomly chosen student plays either sport is 16/29.
 
        
             
        
        
        
Answer:
<em>P=0.0000037</em>
<em>P=0.00037%</em>
Step-by-step explanation:
<u>Probability</u>
A standard deck of 52 playing cards has 4 aces.
The probability of getting one of those aces is

Now we got an ace, there are 3 more aces out of 51 cards.
The probability of getting one of those aces is

Now we have 2 aces out of 50 cards.
The probability of getting one of those aces is

Finally, the probability of getting the remaining ace out of the 49 cards is:

The probability of getting the four consecutive aces is the product of the above-calculated probabilities:


P=0.0000037
P=0.00037%

Answer:
Explanation:
The number of emails is multiplied by <em>4</em> every <em>9.1 weeks.</em>
Thus, since <em>Tobias initially sent the chain letter to 37 friends</em>, the number of letters will grow as per this geometric series:
Start:        37 letters
- In 2 × 9.1 weeks: 37 × (4)²
- In 3 × 9.1 weeks: 37 × (4)³
As you see, the exponent is the number of weeks divided by 9.1
Thus, if your variable is the number of weeks, t, then the exponent is t/9.1
And the exponential function, P(t) will be:
