A spinner was spun 1000 times and the frequency of outcomes was recorded as in given table.

Find (a) List the possible outcomes that you can see in the spinner (b) Compute the probability of each outcome. (c) Find the ratio of each outcome to the total number of times that the spinner spun (use the table)

A coin is tossed 100 times and the following outcomes are recorded Head:45 times Tails:55 times from the experiment a) Compute the probability of each outcomes. b) Find the sum of probabilities of all outcomes.

A die has six faces numbered from 1 to 6. It is rolled and the number on the top face is noted. When this is treated as a random trial. a) What are the possible outcomes ? b)Are they equally likely? Why? c) Find the probability of a composite number turning up on the top face.

If three coins are tossed simultaneously then write their outcomes. a) All possible outcomes b) Number of possible outcomes c) Find the probability of getting at least one head (getting one or more than one head) d) Find the Probability of getting at most two heads (getting Two or less than two heads) e) Find the Probability of getting no tails

A bag contains five green marbles, three blue marbles, two red marbles, and two yellow marbles. One marble is drawn out randomly. a) Are the four different colour outcomes equally likely? Explain. b) Find the probability of drawing each colour marble i.e. , P(green), P(blue), P(red) and P(yellow) c) Find the sum of their probabilities.

A list of things in a house are given in table 2. Name the materials from which each object may possible be made of: (If you don't know which material the objects is made of, discuss with your friends and find out.) How many types of material can be used for making chairs?

Let us do the following activity to understand the mendelian principles of heredity. Materaials required: a. 3cm length and 1 cm breadth chart pieces -4 b. 2 cm length and 1 cm breadth chart pieces -4 c. Red byuttons -4 d. white buttons -4 e. chart, scale, sketch pen penil, 2 bags. Method: Prepare a chart with 2x2 boxes along with numbe and symbol as shown in the figure. Game 1: Monohybrid cross (starting with hybrid parents) To start with take 1,2 or 3,4 . In case you start 1,2 pik all the 16 log and short pieces and prepare such paris in each of which you have a long and short piece. Take 4 pairs each of long and short strips and put them in two separate bags. Now each bag contains 8 strips (4 long and 4short). One bag say 'A' represents mael and the bag 'B' represents female . Now rendomly pick one strip each from bag A and B and put them together in the 1 on the chart. Keep picking out the strips and arrange them in the same manner till your bags are empty. Same time your boxes in the chart are filled with paris of strips. you might have got the following combinations, two long strips, one long and one short strip, two short strips. (Q) D. What is the percentage of each type? also find their ratios.
