If you flip a penny 99 times and each time it came up heads then the chance of the penny coming up heads is ___
Helga [31]
The chances of heads as a result when flipping a penny will always be 50%. Although heads came up 99 times in a row, the events that occurred before will not affect the probability of the current event in terms of a coin flip.

There are 1 out of 2 chances of it occurring or 1/2. Divide that and multiply it by 100% to get the probability in percent. So the answer will be 50%.

The answer is B.

Suppose the rate of plant growth on isle royale supports an equilibrium moose population of 850 moose in this scenario there are
lesya692 [45]

The population of moose will still be around 850 in 30 years.

<h3>What is carring capacity?</h3>

Carrying capacity is the number of individuals that an environment can support without significant negative impacts to the organism and its environment.

With that being said, the moose population size will be same or still 850 after 30 years. Rate of plant growth on isle Royale supported in equilibrium moose population of 850 moose and if there will more 200 mooses arrived then there will be no sufficient plants available to feed those additional mooses. This is the concept of carrying capacity. Carrying capacity is defined as the species average population size in particular habitat. Species population size is restricted by environmental factor like food, shelter, etc. If number of mooses will be increased in particular habitat and plants are limited ,then there will be strong competition between them, which results in survival of the fittest.

So when population size increases on Isle Royale,may be in beginning, for a while there will be sufficient plants to feed those additional 200 mooses, but after some time plant population will reduce and there will be not enough plants to feed all of the mooses. And if needs are not met, population will decreases which allows plants to grow in normal population to feed 850 mooses. So, after 30 years moose population size would be around 850 mooses.
