judy tosses a coin 4 times. draw a tree diagram showing the possible outcomes. what is the probability of?

Question

getting at least 2 tails

Answer 1

The tree diagram will start out with your first toss.
You can get either heads (H) or tails (T)
H T
Then your second toss you can get the same results, but you show branches off your first two outcomes.

H
^
H T

T
^
H T

Continue to do this for two more tosses and that will show you all the parts of the tree diagram. From there you can determine how many possible outcomes you had, and then how many of the possibilities had at least two tails in them.

Hope this helps.

Answer 2

regrettably your question and your clarification of your question are not any more describing the very same ingredient. Your question says "what's the threat of no longer getting 2 heads?" notwithstanding the reason you provide is for a diverse question, which could be "what's the threat of no longer getting * a minimum of * 2 heads?" those are 2 diverse questions, with 2 diverse solutions....(it really is one reason you're seeing solutions that disagree with one yet another). I consider Nicolette on the respond to the question "what's the threat of no longer getting (precisely) 2 heads?" to respond to the different question, "what's the threat of no longer getting * a minimum of * 2 heads", there are 2 diverse circumstances... First, all 4 money ought to nicely be tails (TTTT). on account that there's a 50/50 danger of heads/tails in for each coin, the threat of this example is a million/2 * a million/2 * a million/2 * a million/2 = a million/16 2d, 3 of four money will be tails, and one will be heads - with a a million/16 danger for each certain blend to ensue. TTTH TTHT THTT HTTT on account that there are 4 opportunities, there's a 4/16 danger of this example occuring. upload the opportunities mutually to make certain the perfect danger to no longer get * a minimum of * 2 heads. a million/16 + 4/16 = 5/16 (.3125)

Answer 3

the possible outcomes are
HHHH,HHHT,HHTT,HTTT
,HTHH,HTTH,HTTT,HHTH,
HHTT,HTHT,TTTT,TTTH,
TTHH,THHH,THTT,THHT,
THHH,TTHH,TTHT,THTH
at least two tails 14/20=0.7

Answer 4

uh...half.?
