Vinvika [58]3 years ago

Answer:

p (X= 4) = 0.266

Explanation:

Probability of randomly selected baby elk to survive adulthood = 46%

As per binomial setting

p (X= k)  = \frac{n!}{k! * (n-k)!} p^k(1-p)^{n-k}

Substituting the given values, we get -

p (X= 4)  = \frac{8!}{4! * (8-4)!} 0.46^4(1-0.46)^{8-4}

p (X= 4)   =   \frac{8*7*6*5 *0.44775 * 0.0850306}{4*3*2*1}

p (X= 4) = 0.266

Answer:

<u>D. </u>\frac{2}{3}

Explanation:

<em>Remember,</em><em> in a</em> limit function<em> </em><em>any number greater than zero the limit to infinity is infinity, and for numbers lesser than zero the limit is zero.</em>

<em>P (X) = </em>2^{x} + x^{3}<em />

<em>Q (X) =  </em>x^{2} + 3^{x}<em />

Rearranging the equation q (x) we have q (x) = 3^{x} + x^{2}
