Step-by-step explanation:
A = A₀ ½^(t / T)
where A is the amount left, A₀ is the original amount, t is time, and T is the half life.
4 days is 96 hours, so the amount left is:
A = 600 ½^(96 / 15)

Step-by-step explanation:
Given: Number of cards a box contains = 10 (numbered 1 through 10).
A random card is picked at first instance and is denoted X and then another card is picked from remaining cards and is denoted as Y
Here E(X) = (1+2+3+4+5+6+7+8+9+10)/10 = 5.5
E(Y)=P(X=1) *E(Y|X=1) +P(X=2) *E(Y|X=2) +. .+P(X=10)*E(Y|X=10)
= (1/10) *(2+3+4+ .+10)/9+(1/10)*(1+3+4+..+10)/9+....+(1/10)*(1+2+3+4+5...+9)/9
= (1/10) *(9/9) *(1+2+3+4+5+6+7+8+9+10) = 5.5
Hence, E(X-Y) = E(X) - E(Y) = 0.000
