We should each take these probabilities first individually.
Probability of tails in a coin toss = 1/2
Probability of <span>drawing letter T from the alphabet = 1/26
Probability of 2 tails in 2 coin toss = 1/4
Sample space = {HH, TT, HT, TH}
Add these together since these events happen after another = 1/2 + 1/26 / + 1/4 = 41/52
The final probability is 41/52</span>
Answer:
48 minutes
Step-by-step explanation:
It will take 48 more minutes to finish raking the backyard.
F(x) = -2.5x + 135...where x is the number of weeks, and f(x) = total weight
The answer is 1.72 and if you estimate it then about 2 or 1.75
