A number cube is rolled three times. What is the probability of rolling a number less than 3 each time?
sergeinik [125]

Answer:

1/27

Step-by-step explanation:

The outcomes when rolling a die are 1,2,3,4,5,6

getting less than 3 = 1,2

P( less than 3) = outcomes of less than 3 / total

                        = 2/6 = 1/3

Since the events are independent we can multiply the probabilities

P( less than 3, less than 3, less than 3) = 1/3 * 1/3*1/3 = 1/27

Rate (R) = 25/3<br>Interest = Rs. 350<br>(d) Principal = Rs. 2400<br><br>Find the time (t) ​
julia-pushkina [17]

Answer:

The value of t is 1.75 years.

Step-by-step explanation:

Given that simple interest formula is I = (P×R×T)/100. So you have to substitute the following values into the formula :

i =  \frac{prt}{100}

let \: i = 350,p = 2400,r =  \frac{25}{3}

350 =  \frac{2400 \times  \frac{25}{3} \times t }{100}

350 =  \frac{20000t}{100}

350 \times 100 = 20000t

20000t = 35000

t = 35000 \div 20000

t = 35 \div 20

t = 1.75 \: years
