Spin a spinner numbered 1 to 5 and toss a coin. what is the probability of spinning an odd number
and getting tails on the coin?
a) 2/5
b)3/10
c)4/5
d)none of the above

The correct answer is B. 3/10.

Step-by-step explanation:

1. Let's calculate the probability of spinning an odd number:

We can spin an odd number (1, 3 or 5) out of 5 events, it means that the probability of spinning an odd number is:

3/5

2. Let's calculate the probability of getting tails on the coin:

We can toss a coin and get tails one out of 2 events, it means that the probability of getting tails on the coin is:

1/2

3. These are independent events because the fact that we spin an odd number does not affect the probability of getting tails on the coin, thus:

Probability of spinning an odd number  and getting tails on the coin =

3/5 * 1/2 = 3/10

The correct answer is B. 3/10

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)

the correct answers i think are b. and d.

give me brainliest if it is correct!
