Jesse is playing a game with a number cube with faces numbered 1 through 6. What is the probability of rolling a number that is
lana [24]

Answer:

The probability of rolling a number that is even and a multiple of 3 is \frac{1}{6}

Step-by-step explanation:

The total possible  outcomes of cube = { 1, 2, 3 , 4 , 5 , 6}

Now, let E: Event of getting an even number and a multiple of 3

So, out of all the outcomes, {6) is the ONLY possible favorable outcome.

\textrm{P(E)}  =\frac{\textrm{Number of favorable outcomes }}{\textrm{Total number of outcomes}}

or, P(E) = \frac{1}{6}

Hence, the probability of rolling a number that is even and a multiple of 3 is \frac{1}{6}

<u><em>12 heartbeats=16 seconds</em></u>

<u><em>16+16=32</em></u>
<u><em>36+16=48</em></u>
<u><em>48+16=64</em></u>
<u><em>16-12=4</em></u>
<u><em>12+12=36+8=44</em></u>

<em>Therefore lions heart beats 44 times every 60 seconds.</em>
