Angelique throws a different six-sided dice 120 times.

Alja [10]

The experimental probability of getting a multiple of 3 is $\frac{3}{8}$ .

Given that, Angelique throws a different six-sided dice 120 times.

<h3>What is Probability in maths?</h3>

Probability denotes the possibility of something happening. It's a field of mathematics that studies the probability of a random event occurring. From 0 to 1, the value is expressed. Probability is a mathematical concept that predicts how likely occurrences are to occur.

We know that, $Probability of an event=\frac{Number of favourable outcomes}{Total number of outcomes}$

Number of favourable outcomes =21+24=45

Total number of outcomes = 120

Probability of getting a multiple of 3= $\frac{45}{120} =\frac{3}{8}$

Therefore, the probability of getting a multiple of 3 is $\frac{3}{8}$ .

My Notes OAsk Your Tea The radioactive isotope of lead, Pb-209, decays at a rate proportional to the amount present at time t an

Papessa [141]

Answer:

10.96 hours will take for 85% of the lead to decay.

Step-by-step explanation:

Suppose A represents the amount of Pb-209 at time t,

According to the question,

$\frac{dA}{dt}\propto A$

$\implies \frac{dA}{dt}=kA$

$\int \frac{dA}{A}=\int kdt$

$ln|A|=kt+C_1$

$A=e^{kt+C_1}$

$A=e^{C_1} e^{kt}$

$\implies A=C e^{kt}$

Let $A_0$ be the initial amount,

$A_0=C e^{0} = C$

$\implies A=A_0 e^{kt}$

Since, the half-life of 3.3 hours.

$\implies \frac{A_0}{2}=A_0 e^{3.3k}\implies e^{3.3k}=0.5\implies k=-0.21004$

$\implies A=A_0 e^{-0.21004t}$

Here, $A_0=1\text{ gram}$

$A=(100-85)\% \text{ of }A_0=15\%\text{ of }A_0=0.15A_0$

By substituting the values,

$0.15A_0=A_0 e^{-0.21004t}$

$0.15=e^{-0.21004t}$

$\implies t\approx 10.96\text{ hour}$
