24 kg

Step-by-step explanation:

You start by calculating the linear mass density of the rod:

d = m/L = (40 kg)/(5 m) = 8 kg/m

So for a 3-m long bar, the mass can be calculated as follows:

m = d×L = (8 kg/m)(3 m) = 24 kg

Two events are occurring:

1) Rolling a die
Sample Space = {1,2,3,4,5,6}
Total number of outcomes in sample space = 6
Favorable outcomes = Odd number
Number of Favorable outcomes = 3

Probability of getting an odd number = 3/6 

2) Tossing a coin
Sample Space = {H, T}
Probability of getting a head= 1/2

The probability of getting odd number and head will be the product of two probabilities, which will be = 3/6 x 1/2 = 3/12 

Thus there is 3/12 = 1/4 (0.25 or 25%) probability of getting an odd number and a head in given scenario. 

So correct answer is option C
