Hayden places these four blocks into a bag. A B С He picks one block without looking. What is the probability that the block Hayden picks has a letter on it? . A 1/4 B 1/3 C 2/3 D 3/4

Option D. 3/4

Step-by-step explanation:

From the question given above, we obtained the following information:

Block with letter = 3

Block with symbol = 1

Total = 4

Thus,

Sample space (S) = 4

Event of block with letter (nBl) = 3

Event of block with symbol (nBs) = 1

Finally, we shall obtain the probability of picking a block with letter as follow:

Sample space (S) = 4

Event of block with letter (nBl) = 3

Probability of picking a block with letter, P(Bl) =?

P(Bl) = nBl/nS

P(Bl) = 3/4

Therefore, the probability of picking a block with letter is 3/4.

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
