What is the probability of spinning a number less than 3 or6

Mathematics
1 answer:
Ipatiy [6.2K]3 years ago
8 0

Answer:

Probability of a dice rolling a number less than 3 is 2/6 = 1/3

Probability of dice spinning a number less than 6 is 5/6

Step-by-step explanation:

Number less than 3:

Chances of no. Being 1 and 2, not including 3, is 1/6 individually.

Hence, chances of no. Rolled being lesser than 3 is 1/6 + 1/6 = 1/3

Probability of no. Being smaller than 6 (lesser than 6) Aka spinning 1 or 2 or 3 or 4 or 5, not including 6 is (1/6) x 5 = 5/6

Michael saves $423 dollars a month for college.
alexandr1967 [171]

Answer:

(a). $20,000

(b). The estimate will be lower than the actual amount.

Step-by-step explanation:

We have been given that Michael saves $423 dollars a month for college.

(a). We know that 1 year equals 12 months.

4 years = 4*12 months = 48 months.

\text{Actual amount saved}=\$423\times 48

Since we are asked to find the estimated amount of money Michael will save in 4 years, so we will estimate both quantities as:

423\approx 400\\\\48\approx 50

\text{Actual amount saved}=\$400\times 50

\text{Actual amount saved}=\$20,000

Therefore, Michael will save approximately $20,000 in 4 years.

(b).

The estimate will be lower than the actual amount as we rounded $423 down $23 to nearest hundred that is $400 and rounded 48 up 2 to nearest ten that is 40.

Therefore, the estimate will be lower than the actual amount.
