Card trees. There are 8 cards in a hat: {1 ♥, 1 ♠, 1 ♦, 1 ♣, 2 ♥, 2 ♠, 2 ♦, 2 ♣}. First, you draw one card at random, if the card has number 1, you draw one more card; if the card has number 2, draw two more cards. Let X be the random variable that counts the sum of the numbers that appear on the cards. (a) What is the probability that the sum is 2? (b) What is the probability that the sum is 6? 20 puntos (a) P = 3/14, (b) P= 2/7 (a) P = 1/7, (b) P= 1/14 (a) P = 1/7, (b) P= 1/7 (a) P = 3/14, (b) P= 1/14

step-by-step explanation:

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !
