You have a standard deck of 52 cards (i. e., 4 aces, 4 twos, 4 threes, …, 4 tens, 4 jacks, 4 queens, and 4 kings) that contains 4 suits (hearts, clubs, spades, and diamonds). we draw one card from the deck. what is the probability that the card is neither a face card (jack, king, or queen) nor a heart? 27/52

30/52 or 0.5769 or 57.69%

Step-by-step explanation:

In a standard deck of 52 cards, the number of face cards (F) and the number of hearts (H) is given by:

Out of all hearts, three of them are face cards (jack, king, and queen). Therefore, the probability of a card being EITHER a face card or a heart is:

Therefore, the probability of card being NEITHER a face card NOR a heart is:

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

the probability that a bird is green (.30) is true
